Terribly inaccurate for heart rate!  What a disappointment. See photo of ridiculous readings.

Terribly inaccurate for heart rate! What a disappointment. See photo of ridiculous readings.
I had a F Alta for several years. It was great, and was always functional as expected. I bought a cheap charger and it caused it to burn up and die. It got very hot, burning my fingers. Fitbit sent me a brand new one without any questions. The new one was dysfunctional and would not sync, no matter what. So I got the Alta HR, second hand. It is almost useless except for keeping time, and passing on texts from my iPhone. The app may be an issue as well. It makes graphs that show my HR has been amazingly high all day, up and down( when I know bu checking the watch that it has not been so. I really wanted to know my HR when I slept, because I have OSA; and during exercise. In both cases, it just stops working completely. The minute I step on the exercise bike- no reading. Same as when I go off to sleep. So it may be a combo of trouble between the app and the watch itself. Either way, terribly inaccurate. Really disappointed. I have added a photo of the ridiculous readings for today, while I was sitting in a chair all day. I have a pulse oximeter, so I know.
