Does a decent job of syncing data. The devices themselves do a terrible job at counting steps (at least 2-3x more counted). Not enough watch face choices (Charge 5). Can't open many settings if you have an ad blocker (AdAway), you have to disable it to get at many things (it's the only app on my phone that does that). Crazy you pay so much for a device and can't get all your data unless you pay for premium.
