Answer to: Button missing from side (actuates functions)I can ditto all of the above in the same time frame! I'm at HR #3. It was a replacement one, as mentioned above. It lasted about three months, and now the same thing happened. I cannot believe the company will not correct this fault. Also, I am astounded at the excellent rating this product gets. I will never buy a Fitbit again; however, as I research what are the best trackers, it always comes up as the best!!!!! Amazing to me. I am very angry and disappointed.
