Outlines
😓 Frustration with the cmf Watch Pro 2
The reviewer expresses strong dissatisfaction with the cmf Watch Pro 2, stating that it was a waste of time trying to understand its features. They found it particularly challenging to extract data from the watch for analysis, which is unusual as they typically enjoy this process. The watch's promised Strava integration failed to deliver, with no data appearing. Due to these issues, the reviewer could not perform a standard review and resorted to a qualitative assessment using the cmf Watch app and reference data. They tested the watch during various activities, including cycling and weightlifting, but were disappointed with the heart rate tracking accuracy, which did not align well with their reference device. The reviewer also mentions issues with the watch's GPS connectivity.
🚴♂️ Mixed Results in Tracking Performance
In this paragraph, the reviewer discusses the performance of the cmf Watch Pro 2 in tracking different activities. For indoor cycling, the watch showed some improvement in heart rate tracking compared to outdoor cycling, although it still missed some peaks and dips. The reviewer also attempted to test the watch during weightlifting but found that it failed to detect the expected heart rate peaks, suggesting poor performance in this area. They concluded that while the watch might be suitable for basic smartwatch functions due to its responsive screen, it does not excel as a health and sports tracker, especially when compared to other devices in a similar price range.
💤 Sleep and GPS Tracking Issues
The reviewer analyzes the cmf Watch Pro 2's sleep stage tracking capabilities and finds the results to be only marginally promising, with limited agreement between the two watches tested and the reference device. They note that while the watch can roughly detect sleep and wake times, its accuracy in identifying sleep stages is questionable. Additionally, the reviewer shares their frustration with the watch's GPS functionality, which they found to be slow and unreliable, even in urban environments with only moderate building obstructions. They suggest that potential buyers looking for reliable sports and health tracking might want to consider other options, such as older Fitbit models or Huawei bands, which offer better value for money.

Transcripts
I hate this watch I really really hate
it I just wasted two hours of my life
and none of that has got me any closer
to understanding how good this watch
actually is so better wording might be
that the cmf watch Pro 2 is just a
nightmare to review I normally love
getting the data out of a new watch and
seeing my computer code generator grass
we need to test these watches for their
Sports and Health tracking but that's
just impossible for this watch they
promis Trava integration but it just
doesn't work at least no data appears
for my two watches getting to the actual
data these watches collect is something
I haven't been able to manage but who
knows maybe my personal monkey brain
just wasn't able to figure out it out
all of that means is that this review
will be slightly different from my
normal reviews in two ways first since
I'm not going to be able to access the
raw data which would normally allow me
to make more quantitative plots like
this and this instead it would be more
qualitative meaning we'll just look at
the data from The cmf Watch app side by
side with the data from my references
the second thing that is different is
that I cannot justify spending a lot of
time testing this watch when I cannot
actually get the raw data out so first
I'm going to use some cycling data I
collected yesterday which we will look
at now then I'll collect some more data
during an indoor cycling test and
weightlifting session right after this
and we review that and finally our were
both watches to bed last night and we'll
do the same thing tonight and we'll have
two nights of data to compare against
the Sleep EG reference so let's get to
it and as I said I want to start by
looking at the heart rate tracking
performance during outdoor cycling and I
did two short cycling sessions and here
you can see the result results for the
first session on the top left we have
the heart rate as recorded by the cmf
watch Pro 2 on my left wrist on the
bottom left here we have the results for
the one on my right wrist and on the
right here we have the reference heart
rate which you assume to be correct and
as you can see overall the patterns look
quite different first of all we can in
general see that there's very little
detail in the heart rate recorded by the
cmf watch Pro 2 there's a bit of
deviation right here in the Middle where
both of them detected a dip in my heart
rate but as you can see over all even
between the two watches the patterns
look quite different in the beginning
they are somewhat the same maybe but you
can see for instance during this second
part the one on my right wrist detected
a much lower heart rate than the one on
my left wrist and both of them were
quite a bit lower than the reference so
my maximum heart rate during this
cycling session was about 160 170 BPM
and the watches don't come close to that
so overall this doesn't look very good
so overall I'm not very happy with this
there's not much agreement between the
two watches and the two watches and the
reference so very different results and
here we have the results for the second
cycling session where again I would say
there's poor agreement with the
reference ofice maybe there's a little
bit better agreement between the two
watches but even that isn't very good
for instance right here the watch on my
left wrist detected a peak in my heart
rate which wasn't detected by the one on
my right wrist maybe here in the middle
we see the best agreement and this also
looks somewhat similar to the reference
device but overall very poor agreement
again the maximum heart rate detected by
the reference device is over 150 bpm and
the Watch 2 never detected a heart rate
even close to 150 bpm so overall not a
first good sign but let's actually take
a step back and make it a little bit
easier for these watches let's look at
cycling indoors I'm going to do a
cycling session indoors now where
watches generally have less trouble
tracking my heart rate and as always my
reference is the polar h10 ECG chest
strap and I also have a second chest
strap as a backup so let's see how these
watches do for indoor cycling it's the
next day now and I'm at work and I was
hoping to look at the heart rate results
for indoor cycling and weightlifting for
these two guys but unfortunately I've
forgot the watch that they are connected
to so I cannot look at the results for
my interval indoor cycling sessions the
pattern should look something like this
so with a lot of Peaks and also some
valleys and for weight lifting we expect
some Peaks like this where each time I
did a set of exercises my heart rate
increases so we'll now have to wait
until I'm home to see how these watches
actually did for indoor cycling and
weightlifting I also considered having
Rafel test these watches Rafel what
would you say if I asked you to review
and test one of these cmf watch Pro 2os
they look cool no you're supposed to say
they're ugly I hate them they're stupid
no they're not ugly are they really bad
so far yes I don't want to invest any
more time I wouldn't want to waste your
time then I don't want to test them
please right answer there's the bin wow
it's really SP okay I'm home now it's
now time to look at the watches side by
side with the reference and see if they
did any better with these other
exercises so cycling indoors and
weightlifting let's take a look at my
computer here and here we have the
results for spinning with the reference
on the right the watch on my left wrist
on the top left and the one on my right
wrist on the bottom left and as you can
see this looks a little bit better than
what we saw for cycling outside so we
see some of the same patterns but we see
for instance at the watch on the top
left misses some of the dips here in the
beginning and also a peak right here and
also the watch on my right wrist shows
some major defects we see missed a
complete Peak right here also this peak
was not completely tracked and here one
of the dips was also missed so it does
look a little bit better it's not
complete nonsense what it's tracking but
also not very good but let's take a look
at weightlifting now and the results for
weightlifting are right here with the
reference on the right where each time I
did a set of exercises I had a peak in
my heart rate and as you can see neither
of the watches really detected these
Peaks they might have detected them a
little bit but as you can see most of
the time the peak in my heart rate was
around 113 BPM and this was basically
never reached by these watches there's
this weird Peak right here in the
beginning for the one on my right wrist
but otherwise they never went over 100
BPM so for weightlifting it isn't very
good all right that really doesn't look
good in terms of heart rate tracking for
the cmf watch Pro 2 maybe for cycling
indoors it's okay it detects quite a lot
of the Peaks at least partially but for
cycling outside and for weightlifting it
doesn't look very promising again this
is a very initial review I cannot get to
R it and I don't want to spend the time
on this watch if I can't but it will
give you a first impression at least of
the performance of this watch and please
also compare to the first generation of
the watch which I'll link up here but
let's next take a look at sleeve stage
tracking maybe this is a bit better
again I cannot do this quantitatively
but just qualitatively and I just
analyzed the two last nights of data
based on my EG reference on this Windows
laptop right here a cheap one from
Amazon so let's see how it did and here
we have the first night I wanted to
share with you now on the bottom here we
have the reference device where you can
see the sleep stages along the vertical
a
and the time along the horizontal axis
and I tried to align the results for the
two watches so the one on my right wrist
here in the middle and the one on my
left wrist on the left as good as I
could with the reference device and as
you can see there is some agreement so
some of the deep sleep so slow wave
sleep s SWS here detected by the
reference device is also detected right
here in Red by the two watches but it
doesn't match that well honestly and you
can also see there are quite some
differences between the two watches some
parts degree quite okay between the
watches so here in the end for instance
and here in the middle well you can also
see that here in the beginning there's
quite a big differences and also R sleep
agreement which you can see in red right
here according to the reference and in
Gray right here according to the two
watches this also doesn't look that good
honestly there's some agreement so this
second third and fourth R sleep segment
detected by both watches somewhat
overlap with the reference device but
not perfectly and it also detects much
less Ram sleep and a bit of extra Ram
sleep right here for this one watch and
right here for this watch so overall to
me this doesn't look very promising but
let's look at the second night the
results for the second night are
displayed right here with again the
reference on the bottom the watch on my
right wrist here in the middle and the
one on my left wrist here on the top and
as you can see again I would say there's
only a marginal agreement let's first
look at Ram sleep again in red according
to the reference device we can see that
the reference device detected 1 2 3 four
five Ram sleep segments and these really
don't seem to align very well with the
sleep stages as detected by the two
watches so the watches detected both one
two three four Ram sleep segments and in
position they also don't match very well
at the reference device so at a start
that already doesn't look very good now
in terms of deep sleep we also don't see
very good agreement we can see that the
reference device mostly detected deep
sleep here in the beginning of the night
and this overlaps somewhat with the
reference devices but not very good
honestly and the watches also de quite a
bit of deep sleep here in the middle and
even near the end of the night a lot
more than the reference device does so
overall to me this doesn't look very
promising and again there's also only
marginal agreement between the two
watches so if the two watches them s
cannot agree I cannot trust their sleep
stage tracking honestly the one thing I
can say is good about the Sleep stage
detection of these watches is that they
detect about the same time I fell asleep
and the same time I woke up so you could
potentially use to detect your total
time in bed but that's about it I
wouldn't trust it to do anything else
and that's not all we didn't discuss
this yet but this watch also has GPS or
at least it's supposed to have GPS I
always tried to start my workout with
GPS but it always took forever to
connect and it basically never connected
while I was waiting for it to connect
and sometimes I waited for minutes yes
there were some buildings around not
super tall ones but some buildings at
least but I always started them at the
same place where I always do my testing
and other watches have no problems there
so I don't know what they want most
people will do workouts inside the city
as well and if it doesn't work for that
why do we even have GPS in this watch
and at R just doesn't have it at least
that's my experience I just got super
frustrated waiting for it to connect and
in the end after a few minutes I just
always gave up by the way I hope that my
testing has earned a subscribed from you
and also leaving a comment or liking
this video really helps this channel now
back to the testing as you might have
guessed overall my experience with the
Sports and Health tracking of the cmf
watch Pro 2 just isn't very good I
couldn't do a full review that isn't
because I didn't want to make one I just
wasn't able to get the data that I
needed to do a quantitative analysis now
looking Beyond health and sports
tracking the watch in itself isn't bad
the screen is pretty good it's
responsive and bright enough so at least
in that sense it's not bad at all and
given the price it might make a decent
Smartwatch it just isn't a good health
and Sports Tracker at least on on me as
always this testing is just on me so
also check out some other reviewers now
if you're in a market for a sports or
health tracker and your budget isn't as
high I would personally maybe buy an
older generation Fitbit or a w hway band
both of these are much better Sports and
or health trackers and check out these
videos up here now these are just two
examples of health and sports trackers
that are better value for money in my
personal opinion if you're mostly
interested in sleep tracking and sleep
stage tracking check out this video
right here for my top recommendations or
if you're more into heart rate tracking
check out this video right here if
you're interested in anything else also
