I bought this watch based on good reviews. But unfortunately I didn't have the same great experience. It takes a few times to get to the next screen, accuracy sucks. I bought it because I suffer from insomnia and wanted to track my sleep. I can confidently deny that I slept 8.1 hours. The app is awful, doesn't sync to my watch at all, doesn't show any data to display. Fitbit had to leave very disappointed.
