I missed the returned window. So I can’t return. Difficult to set. Is not accurate for hours of sleep. I do not like the manner in which you charge this watch. You have to take it out of the strap and plug in. I hate that. I will then forget to put it back on after charging. It keeps the time accurately. But I wanted to know about my sleep. Not accurate. I hope I’m getting more than 2 hours of sleep. I don’t recommend.10/21/2020 The fitness tracker will no longer charge. I’ve been trying to charge it for the past 3 days. Using different chargers. I’m changing my review to one star. Wish I could give it Zero stars. Please don’t waste your money.
