📌 Introduction to Amazfit Balance Review
The script introduces the Amazfit Balance smartwatch, highlighting its new biot tracker 5.0 PPG sensor that offers improved heart rate tracking. The reviewer, Rob, a postdoctoral scientist specializing in biological data analysis, shares his initial impressions and plans to test the watch's heart rate tracking during various exercises, sleep stage tracking, and GPS accuracy. Historically, Amazfit devices have not performed well in Rob's tests, but the Balance seems to break this trend. Despite this, Rob finds the Balance's design chunky and less appealing compared to other Amazfit models. The focus is set on objective testing rather than subjective design opinions.
🚴♂️ Heart Rate Tracking During Indoor Cycling
Rob tests the Amazfit Balance's heart rate tracking capabilities during indoor cycling, comparing its performance against the Polar H10 ECG chest strap, known for accurate readings. The results show a generally good agreement with a correlation of 0.95, indicating a reliable performance. However, there are occasional discrepancies, particularly when the heart rate decreases, where the Balance overestimates. Despite these minor issues, Rob is satisfied with the Balance's performance for indoor cycling, considering it a significant improvement over previous Amazfit devices.
🏃♂️ Heart Rate Tracking During Running
The script details Rob's testing of the Amazfit Balance's heart rate tracking during outdoor running. Despite the increased physical movement and potential for less accurate readings due to arm tension and bumpiness, the Balance maintains a strong correlation of 0.95 with the Polar H10, suggesting it does not suffer from cadence lock and can accurately track heart rate. Individual run analyses show only minor deviations, confirming the Balance's reliability during running.
🚴♀️ Challenges in Outdoor Cycling and Weightlifting
Rob discusses the increased difficulty in tracking heart rate during outdoor cycling and weightlifting. Outdoor cycling introduces more arm tension and movement, which typically hinders accurate heart rate readings. The Balance struggles with this, showing a lower correlation and missing several heart rate peaks. Weightlifting, another challenging exercise for heart rate tracking, also presents issues for the Balance, with many peaks missed and a correlation of 0.74, indicating less reliable performance. Comparatively, the Balance performs better for indoor cycling and running than for these more dynamic activities.
💤 Sleep Stage Tracking Evaluation
The script describes Rob's evaluation of the Amazfit Balance's sleep stage tracking capabilities, compared to a zMAX EEG headband known for measuring brain waves. The Balance shows only about 40% agreement for deep sleep, with more time incorrectly categorized as light sleep. Light sleep agreement is about two-thirds, and REM sleep agreement is roughly 53%, with significant confusion with light sleep and awake times. Individual night analyses reveal a mix of accurate and inaccurate sleep stage detections, suggesting the Balance is not reliable for detailed sleep analysis but may provide a rough estimate of total sleep time.
🚴♂️ GPS Tracking and Final Thoughts
Rob tests the Amazfit Balance's GPS tracking by cycling the same route multiple times and observes the signal overlap. The Balance shows some noise in signal acquisition but generally acquires the signal quickly. Throughout the routes, the GPS signals are relatively close, with occasional deviations. While not perfect, the GPS performance is better than expected. In conclusion, the Balance offers improved heart rate tracking over previous Amazfit models, especially for static exercises, but struggles with more dynamic activities and sleep tracking. Rob gives the watch a tentative rating of three out of five stars, acknowledging its的进步 but also its limitations.

Transcripts
amazfit finally made a watch that
doesn't totally suck this is the amazfit
balance which has the new biot tracker
5.0 PPG sensor which makes this the
first amazfit device I tested that
actually measures my heart rate at least
somewhat reliably it definitely isn't
perfect but it might just be good enough
in this video we're going to test the
hard rate tracking performance of the
amaz Fit balance during different types
of exercises and we'll additionally test
the Sleep stage tracking performance and
the GPS tracking accuracy of this new
amazfit device as always I don't want to
waste your time so there are time stamps
on the timeline let's get
started hello everyone for those of you
that are new to the channel my name is
Rob and I'm a postdoctoral scientist
specializing in biological data analysis
now amazfit devices have historically
performed terribly in my testing and
like I said the amazfit balance is the
first watch to break this trend sadly
the one thing that a maze fit generally
does do very well does not flag back in
this watch namely the nice design of
most of their watches amazfit devices
generally have quite beautiful screens
and a good design but I personally find
the am F balance quite chunky and not so
goodlooking however that's a subjective
opinion and that's not what you're here
for let's focus on some objective
testing instead and let's start with the
heart rate tracking performance I'll
start off by looking at the performance
of the Amit balance during indoor
cycling which is a relatively easy
exercise for watch the track given the
limited movement and of tension on my
arm and here you can see an overview of
those results now to test the
performance I'll compare the heart rate
measurements of the amaz with balance
against the polar h10 ECG Jaz strap
which can generally record my heart rate
very accurately now each dot in this
plot is a single heart rate measurement
with along the horizontal axis the value
according to the polar h10 ECG chest
strap and on the vertical axis the value
according to the amaz Fit balance now
the closer the points are to this blue
line right here the better the agreement
and and the darker black the color mod
that there are and as you can see
there's generally a pretty good
agreement between the polar h10 and the
amaz Fit balance most points are on or
at least close to the blue line and the
correlation which is this r value up
here is also quite high at
0.95 the maximum value of this
correlation is 1.0 so a correlation of
0.95 is really good there are a few
points away from the Blue Line
especially below it right here but still
this doesn't look too bad but we really
need to look at those individual bike
rides to see what's going on and here
you can see that first example interval
spinning session where we see a pretty
decent agreement between the amaz Fit
balance and the ECG chest strap now
along the horizontal axis we have the
time and my heart rate is on the
vertical axis with in blue green my
heart rate according to the polar h10
ECG chest strap and in red my heart rate
according to the amaz with balance and
for this ride most of the time the heart
rate was correctly detected only right
here where I had a DE decrease in my
heart rate did the M balance detect an
increase in my heart rate so detected
about double my heart rate right here so
it detected a heart rate of about 140
BPM I would say whereas in reality my
heart was about 70 BPM so it probably
had a bit of a noisy signal but this is
the exception rather than the rule
looking at my next spinning session we
see this looks quite good most of the
time my heart R agrees between the polar
h10 and the amaz with balance and that's
also what we see for this bike ride
right here though again there's one art
effect right here where it all of a
sudden detected an increase in my heart
rate but as I said this is the exception
rather than the rule because for most
indoor cycling sessions it looks rather
good like for instance right here and
also right here there is some minor
deviation for instance right here a
slight delay in it picking up an
increase in my heart rate but overall
I'm quite happy with the performance of
the mid balance during indoor cycling so
that's not looking too bad there are
some small artifacts but nothing much to
complain about compared to other older
MV devices is this is actually great
performance but let's take a look at how
this watch Compares and we will do that
by comparing the performance of the M
with balance to many of the other
devices I've tested in the past and that
overie is displayed right here the
correlation value I was talking about
before is the metric we will use for
this which is displayed along the
horizontal axis here we want that value
to be as close to one as possible on the
vertical axis actually order to watch us
from worst to best so the further to the
right and the higher devices the better
is its correlation with the ref device
and I marked the Amit balance in red
right here and as you can see compared
to all other watches out there it's in
the upper middle class of watches it
isn't amazing as the Apple watches up
here are for instance but it's
definitely decent and probably good
enough what is important to know is that
many of the other amazfit devices are on
the bottom right here and right here so
out of the bottom eight watches right
here one two three four five six were
amazed with devices so this is really a
significant Improvement all the way up
here but let's zoom in a bit so we can
actually read those labels and that
zoomed infus is played right here so
these are just the watches with a
correlation of 0.9 or higher and as you
can see even amongst these better
watches the maze Fit balance is doing
quite decently it's quite close to the
Fitbit Lux the Huawei watch 3 and the
polar Varity sense for instance so this
doesn't look too bad there are
definitely better devices out there
especially Apple watches some Huawei
watches but also Google pixel watches
and Samsung Galaxy watches aren't bad at
all but I also suspect that this
performance of the amaz with balance is
good enough for most people so that's
not too bad at all but we haven't really
challenged the amaz with balance so
let's do that let's now take a look at
the next most difficult exercise for
watch the track running outside now
running outside increases the bumpiness
during the exercise however there's
still little tension on my arm and on my
wrist so this is only slightly harder
for the watch you get a clean heart rate
signal let's see how the amaz with
balance did and you can see that overiew
right here but now for running and as
you can see the agreement is still very
good the correlation is very similar at
0.95 and all values are on or close to
the blue line or most measurements at
least there are a few below it for
instance right here and also right here
and a few above it but the deviation is
quite minor so this looks good for the
ma with balance it doesn't seem to
suffer from Cadence lock where it meses
your Cadence instead of your heart rate
but let's take a look at the individual
runs to see where there's still some
points below and above the blue line and
here you can see the results for my
first run with again the polar h10 in
blue and the amaz Fit balance in red and
there's generally a good agreement
between the amaz set balance and the
polar h10 there are some minor deviation
for instance right here and also right
here but generally this looks very good
and that's also we see for the second
run right here though in the beginning
it missed my heart rate for a while
before it caught on but after it
acquired the heart rate signal it
actually looks really good and that's
also what we more or less see for this
example run right here though here it
did struggle a bit in the beginning
right here but later on it looks really
good and that's also true for this final
example I wanted to show you here it
struggled a bit near the end but overall
not a bad performance so here we have a
similar overie to before but now for
running so again the further to the top
right the better device and as you can
see there has far fewer devices in this
overiew because I only recently started
running so I don't have data for that
many watches but as you can see the amaz
with balance is actually doing quite
good again Apple watches are some of the
top performers out there but the amaz it
balance isn't half bad I would say it's
good enough for most people it's really
close to for instance some Huawei
watches and also some pixel watches so
I'm not disappointed by this so we saw
some small artifacts again but the
correlation is still quite high I would
say at roughly 0.95 however let's now
make things even more difficult by
looking at the performance of the amazit
balance for outdoor cycling now cycling
outside increases the tension on my arms
because I have to all on to the
handlebars there's also much more
movement and bumpiness making it much
harder for a watch to get a clean heart
rate signal I tested the MH balance for
a total of 21 bike rides I have for
first a quick S note if you're
interested in the latest updates on the
wearables I'm testing I'm planning to
start back up with my newsletter and
posting more Optical things on my
Instagram and my YouTube shorts channel
so if you're interested in any of those
those are linked below also I'm trying
to become part of the first people who
receive watches to review from companies
like Garmin Samsung and mafit and if you
want to help me make faster and better
reviews it would really help if you like
subscribe and or comment but of course
this is totally up to you now enough
self- promotion let's get back to
testing the amaz with balance and that
overview is displayed right here so this
is a similar overview to before but now
we're biking outside and as you can see
this is where the amaz with balance
starts a struggle there are still some
points close to Blue Line or at least
the majority is still close to the blue
line but there are many points below the
blue line right here so there's this big
triangle right here of points below the
Blue Line indicating that in these
moments the watch detected a two low
heart rate the correlation is also much
lower at 0.65 where before the
correlation was 0.95 for both running
and cycling inside cycling Outdoors
really makes the watch struggle but
let's take a look at the individual bike
rides to see what's going on here and
here we have the first example bike
right with again the reference in blue
green and the mafit balance in red and
as you can see the agreement is not
amazing there's generally quite a delay
in it picking up an increase in my heart
rate so it does seem to catch up over
time but it really needs a bit more time
to get those peaks in my heart rate you
can see that right here but also right
here right here and right here so each
time I have a sudden increase in my
heart rate it really struggles to keep
up that's what we see to a higher or
lower degree in many of the bike rides
so for this bike ride right here it
didn't struggle as much during the
second part but during the first part it
had some issues for this bike ride it
actually looks quite good so there's not
much to complain about also this one
doesn't look that bad then for this bike
right where it did detect my heart rate
it was quite good though it missed my
heart rate for a large part of the ride
so somehow it lost the signal right here
and then for other bike rides we again
see a delay in it picking up an increase
in my heart rate you can see that
especially near the end of this bike
ride right here and also for this bike
ride it either had the delay or it
completely missed a peak in my heart
rate as you can see right here so it's a
bit of a mixbag some bike rides look
okayish I would say this one looks
okayish though it still has its issues
the other are quite a bit worse where
for instance right here it misses a
large part of the peak right here so be
aware that at least on medium as balance
is struggling a bit and again this is a
similar overview to before but now for
biking outside and as you can see the
amazfit balance marked in red isn't
amazing it's not the worst device out
there which again are other amazit
devices so the top five worst performing
watches here are all amazit devices so
for instance the amaz with bipu Pro but
also the amazfit T-Rex Pro and GTS S2
mini and also some newer ones like the
GTR 4 aren't doing great amazfit devices
are really some of the worst devices out
there at least up until the Amit balance
which is doing quite okay for most
exercises but it's not amazing for
biking outside as you can see right here
most devices are doing better than the
amaz with balance for biking outside so
I wouldn't really recommend it for that
type of exercise and again Huawei
watches Google pixel watches and
especially Apple watches are doing a lot
better so while biking out outside the
amaz with balance didn't perform as well
as it did for instance for indoor
cycling and running it missed a
significant number of peaks in heart
rate and also has some delay in picking
up on changes in my heart rate so if you
want to use it for outdoor cycling I
wouldn't recommend it now before looking
at the Sleep stage tracking test let's
take a look at the performance of the
amaz with balance while weightlifting
this is generally also a very hard
exercise for many watches to track and
here we have that overview similar to
before but now for weightlifting and as
you can see it looks okay okay it's not
as bad as what we saw for outdoor
cycling so the correlation at 0.74 is a
bit higher than what we saw for outdoor
cycling which I believe was 0.64 0.65
but it's definitely not as good as what
we saw for indoor cycling and running
which has a correlation of
0.95 and that's probably due to it
sometimes detecting a to low heart rate
especially here in the higher heart rate
range it almost always attacks it to low
heart rate this indicates to me that
most likely the individual sets that I
do it cannot pick up on those peaks in
my heart rate but let's take a look at
the individual weightlifting sessions to
see what's going on here so here we have
the first example weightlifting session
I wanted to show you with again the
reference in blue green and you may Fit
balance in red with the peaks in my
heart who representing each set that I
did and as you can see the peaks in blue
aren't completely followed by the
amazfit balance in red some of the Peaks
are somewhat detected for instance right
here and right here but many of them are
missed and this is what we see for many
of the weightlifting sessions some of
the Peaks are caught but many or even
most are missed and I would say the amaz
with balance isn't that reliable for
weightlifting and again here we have a
similar overview to before but now for
weightlifting and here the amaz FD
balance is somewhere in the middle I
would say you can see it marked here in
red it's not amazing and also not
terrible though generally I wouldn't
recommend using any device with a
correlation of 0.9 or preferably even
0.95 or high for weightlifting you
really want decent performance and you
also want it to pick up on those peaks
in heart rate and the amaz with balance
just doesn't do it but that's true for
most watches out there it's just really
difficult to track your hard during
weightlifting if we zoom into the best
performing watches we can see that only
some selected Huawei watches Apple
watches and also some Google products
like the pixel Watch 2 and the Fibber
charge 6 are decent during weightlifting
other watches I would really not
recommend and if you want accurate heart
rate tracking during weightlifting my
general recommendation is to use an ECG
chest strap like for instance the polar
h10 this doesn't suffer from that
tension on your wrist in your arm so
it's just much more reliable but if you
don't find it comfortable one of these
devices is probably your best bet so for
weightlifting the amaz with balances Med
the Yer I would say it isn't as bad as
some of the other devices out there but
it definitely isn't good it misses many
of my peaks in heart rate so I wouldn't
rely on it for weightlifting still
overall it showed a significant
Improvement compared to basically all
other amaz devices out there and it did
quite well for two easier exercises
cycling indoors and running but it
struggled during weightlifting and
outdoor cycling therefore overall i'
give the hard rate tracking of the amaz
balance three to maybe even three and a
half out of five stars next let's take a
look at the Sleep stage tracking of the
amaz F balance which I tested during a
total of seven nights now to test the
Sleep stage tracking performance I'll
compare the amaz F balance to the zMAX
EG headband which can actually measure
my brain waves now this device also has
its limitations especially when it comes
to to detecting awake time I discussed
this in several of my videos so I won't
go into details here but what it boils
down to is it'll mostly ignore the awake
time detection in the analysis and here
I show an overview of the sleep test
results now on top are the sleep stages
as recorded by the zMAX eug device and
on the left are the sleep stages as
recorded by the amaz with balance now
each column here sums to 100% meaning
that we can see what percentage of each
of the sleep stages according to the
zMAX was predicted as each sleep stage
body M with balance and if they
perfectly agree all values on the
diagonal should be 100% now first of all
we see that only about 40% of what was
deep sleep according to the EEG device
was also deep sleep according to the
amfit balance so that doesn't look very
good more was actually predicted as
being light sleep instead now light
sleep agreement is okayish I would say
about 2third of what was light sleep
according to the EG device was also
detected as light sleep by the am F
balance however a significant amount is
actually being confused as RAM sleep in
sted about 25% now Ram sleep agreement
also isn't that great though not as bad
as I initially feared at about 53% and
most confusion was with light sleep at
about 27% but a lot of it was also being
confused as awake time instead now as I
said before we're not going to focus on
the awake time detection but just for
completeness only about onethird of what
the zMAX detected as a wake time was
also detected as a wake time by the
amazit balance but the zMAX actually
tends to detect a lot of short awake
moments that I'm not sure are really
relevant so we're not going to focus on
this too much luckily most confusion was
with light sleep which makes sense
actually as light sleep is the closest
Sleep stage to being awake but again
we're not going to focus on the awake
moments we're mostly going to focus on
this part right here so with the Deep
Sleep light sleep and R sleep and for
the amaz Fit balance it's actually
really interesting to look at the
individual Knights to help us better
understand what's going on here and here
we have the first Knight I wanted to
share with you on top we have the sleep
stages according to the zMAX EG headband
with along the horizontal AIS the clock
time and my sleep St stages on the
vertical axis and on the bottom we have
a similar plot but now for the amid
balance now in purple right here I
highlight the deep sleep as recorded by
the zMAX EG headband and as you can see
there's a marginal agreement between the
zMAX and the amid balance some of the
deep sleep that the zMAX detected was
also detected by the amaz with balance
about half of it which matches that 50%
that we saw before but the amaz with
balance also detects some extra deep
sleep and for this second night we see
more or the same thing some of the Deep
Sleep detected by the zMAX is also
detected by the amid balance again
roughly half I would say but also some
extra deep sleep is detected and that's
more or less the general pattern that we
see though there are some better kns
like this one right here for instance
now as I mentioned before Ram sleep
agreement is okay though not amazing you
can see that right here for instance
where some of the ram sleep segments
detected by the EG device were also
detected by the amid balance for
instance right here right here and right
here but the am balance also detects
some extra Ram sleep for instance right
here and right here and it also misses
some Ram sleep that's more or less the
general Trend that we see though some
Knights are better like this one right
here and some are not as great like this
one right here so it's really a bit of a
mix so that doesn't look terrible but
also not great so I wouldn't really rely
on it as I said I'm not going to focus
on the awake moments marked in green
here according to the EEG device because
there are just so many of these short
awake moments that the EEG device
detects that I'm not sure that
interesting but we can generally see
that the amaz balance roughly detects
when you fall asleep and when you wake
up we see that for most nights also
right here it doesn't look too bad for
my falling asleep and waking up moment
though I had a bit of a slumbering face
right here where the amaz with balance
detecting me as being awake all of the
time still overall it looks pretty okay
and we see something similar right here
where again I had a slumbering face and
the amaz with balance just decks me as
being awake but still generally for
getting an estimation of your total time
of sleep this doesn't look too bad okay
that's honestly not very encouraging it
doesn't seem like a totally random
result but it's definitely not good and
there are plenty of better devices out
there believe me and to prove that to
you let's see how the am withit balance
performs compared to other watches that
will help us put these results into
perspective now this graph right here
shows you an overview of the agreement
of different watches with different
reference devices along the horizontal
axis we have the average agreement over
the individual sleep stages and on the
vertical axis we have the agreement of
the worst sleep stage now a better de
agreement the more to top right to
devices and this overview is slightly
complicated because I use different
reference devices so the devices not
marked in any color were tested against
the dream 2 EG had been my general
reference but dream went bankrupt so I
cannot use it anymore the devices marked
in blue purple were tested against
polography so the gold standed in sleep
stage tracking and the devices marked in
green were tested against the zMAX EG
headband so the same device we're using
in this test today and you can see the
amaz fit balance marked in green right
here so it's really amongst the lower
performing watches I would say it's not
as bad as for instance the Mi band but
it's also not nearly as good as many of
the other devices out there especially
Apple watches are very good sleep stage
trackers but also the eight Sleep p 3
aura rings the pixel watch and even the
whoop strap are pretty decent sleep
stage trackers and the amazit balance
just doesn't come close so I really
recommend just using the amazit balance
for tracking your total in bed maybe
your total sleep time but not more than
that so the Sleep stage tracking
performance of the amaz with balance is
basically what I expected it to be like
it's not something I would rely on I
think it can be used to get an estimate
of your total time spent in bed but
that's about it I wouldn't use it for
anything more detailed therefore I'd
give the Sleep stage tracking
performance of the amaz with balance two
out of five stars next we're going to
take a look at the GPS tracking
performance of the amaz with balance I
tested the GPS tracking performance by
by cycling the same route several times
and seeing how well the signals overlap
let's take a look and here you can see
the results for six times I cycled back
from work now I always started my ride
either right here or right here and I
didn't give the watch any extra time to
acquire the signal and as you can see
there is some noise in the moment it
acquired the signal so this ride right
here for instance I probably started all
the way down here and it took some time
for it to acquire the signal and if we
zoom in a bit to these four rides right
here all of them are supposed to start
roughly in front of this building right
here and you can see definitely there's
a bit of noise in when it acquired a
signal one time the signals all the way
down here and I'm not sure what it is
I'm not sure if this is a very late
acquisition and I actually started it
all the way back there where also this
one was started or if it was actually
started down here and it's noisy still
the signal acquisition isn't perfect but
it definitely doesn't take a lot of time
for it to acquire the signal so might be
good enough for most people you might
just have to wait a little bit for it to
get the signal and if we then look down
the route we can see it's a bit noisy
though not terrible there's one signal
which is very deviant right here others
are actually relatively close to each
other and this one keeps deviating quite
a bit also one more signal is deviating
a bit right here and if you go down the
route there's always one or two signals
that are deviating a bit and the others
are relatively close it's not terrible
actually many of the signals here are
super close and this looks better than
some other watches let's zoom out a
little bit if we go down the rout we can
see the signals are actually not that
far away from each other it actually
looks quite decent here I took different
routes you can see one time I went along
here and one time along here but the
signals stay quite close together
usually here near the radio tower
there's a bit more deviation and we can
also see that right here there might
actually be some signals coming from
right here that are interfering still
overall this doesn't look too bad
honestly the signals are relatively
close together and there are many
watches that are doing worse there are
some better devices out there like for
instance the Apple watch and especially
Garmin watches but this doesn't look
that bad to me but let's take a look at
some rides to work to see what these
look like and these are displayed right
here I only have three rides for this so
these are three times I cycled to work
here we can see that the signals always
acquired very quickly and very
consistently I always started it on the
corner right here so there's a bit of
deviation right here but this doesn't
look too bad and if we zoom out a bit we
can actually see that the signals are
relatively consistent now we're only
looking at three signals right here so
there isn't as big of a chance of a
deviating signal but generally if we go
along the Route it actually looks quite
decent it's not amazing there is some
deviation also right here and right here
but it generally doesn't look too bad in
my opinion if we go along the Route even
further there's generally a relatively
small deviation between the signals but
you can judge for yourself compared to
some of the other watches I've tested in
the past where I take a similar route
overall I'm actually not that
disappointed yes there is some deviation
it goes a bit away from the road but
overall this is relatively consistent
and for a device like this I actually
expected worse performance so overall
not bad so the GPS tracking performance
of the amaz Fit balance isn't half bad
it isn't amazing but it's actually
better than I expected I always find it
difficult to put an actual number on it
without actually quantifying it but it
probably give the GPS tracking
performance around three to maybe even
three and a half out of five stars
before getting to my final conclusions
of course there's many limitations to my
testing the main one being that I just
tested it on myself with whatever
firmware was available at the time now I
tried to summarize my final judgment on
the amazfit balance and I find myself
struggling somewhat I saw you can now
get it for about $200 which isn't
terribly high it's not cheap but it's
also not the most expensive watch out
there it also has a good battery life at
about 2 weeks and the watch is
significantly better than anything amaza
that's produced so far however it still
isn't that great it has quite good heart
rate tracking for more static exercises
but it really struggled for cycling
outside and weightlifting the Sleep
stage tracking also wasn't that great
the GPS tracking performance on the
other hand wasn't too bad also and I
know this is more subjective I really
don't like the way it looks a mafit
generally does such a good job making
watches with a really nice screen and a
relatively slim design and this thing is
just a bit too bulky for me but of
course that last part is very subjective
all in all I'd probably give this watch
three out of five star bars mafit has
definitely improved their heart rate
tracking which is good but they've got a
bit to go before I would strongly
recommend any of their watches of course
also check out some other reviewers if
they reach different conclusions if you
do decide to get an amazfit balance an h
s pot 3 a whoop strap an order ring
another device or anything at else on
Amazon for that matter even something as
small as toilet paper want to
potentially save some money and at the
same time support the channel their
different affiliate and non-affiliate
links in description below they do not
cost you any extra and some even
discount also given that you made it to
the end of this video on the amazfit
balance check out my other reviews of
amazfit devices as well and also my top
General recommendations in the meantime
thank you so much for watching and catch
you in the next
