Number 1 issue is the ridiculous sleep display, totally not useful or readable. The battery wears out so fast, have to charge it every couple days. Sleep isn’t being recorded properly nor is the O2. Seems to me that with all the negative comments, Fitbit should do a proper update and fix all this crap. I’ve used Fitbit for years and I’m finally switching to another smart watch. Everything I liked about my charge 5 is wrong now. Too bad.
