LIKED: you can talk on a call thru watch (but not a big deal for me) and has voice command feature (i probably never would have used it but cool) … DISLIKED: No notifications from phone calendar alerts (very big deal for me) ; custom face only shows the pic you set, the time, and # of steps (no title) only – so No date shown, weather, heart rate, etc & wasn’t compatible with Facer ; wouldn’t sync my favorite contacts (limited to 100 numbers) but caller id name showed when called so its ok i guess ; if media sounds set to play from watch, media will not play on phone (optional feature) but that is annoying when you scrolling social media without watch on ; uses 24mm for spring bar but i needed 20mm (so i wouldn’t have to replace all my bands from prev watch)
