My heart rate is often very wrong. It'll show 80 - 110bpm during a workout but my checking manually and via heart monitor will show 120 - 150.
I have fitted the watch. Cleaned it. Synced it. Turned it off and on again. On the opposite wrist... etc. The same workout will show 250cals one session then 110 the next. But then it'll work during a run. Then back to not working.
I'm about to throw the whole watch out. This is affecting intensity minutes, calories and Vo2 max. I feel like I spent hundreds on this watch that was supposed to help me improve my health and its totally unreliable.
