- Sleep tracking is pretty unreliable, while it tracks sleeping time ok, the score I feel is not very accurate.
- Walk auto detection is unreliable, sometimes it won't just start, if you stop walking for a few minutes to take a break, it stop the tracking too soon, won't resumes correctly or sometimes just won't start at all.
- Spo2 is unreliable, when I had covid it was totally useless and I purchased a cheap spo2 finger device.
- Physical age on the watch (in settings, user profile) didn't update when I'm now one year older and while it is updated correctly on Garmin Connect and I already reached max attainable goal.
- Vo2 max doesn't update that regularly if the only thing you do is walk (that should be enough, I walk every day).
- Pairing is unreliable, disconnect if you move the cable just a little bit.
- Once I got the device stuck after an update, had to hard reset to rescusitate it while I never use beta version.
- Recently Garmin connect kept asking me for login / password, until I removed the device from the app.
Otheriwse, it's a good device, but need progress.
