Big disappointment.
1. Metal band is junk. Cheaply made and difficult to adjust for proper fit. Looks like a cheap add-on instead of looking like it was made for the watch.
2. Tachy numbers around outside of watch are unreadable because color is almost same as metal body.
3. Color of watch and band do not match. Watch is dark gray, band is black.
4. Can't set alarm from watch. Have to do it from phone.
5. Watch face selection is very limited.
6. App is very limited. There are not many options for setup.
7. Setup is very primitive. Can't go back one step. Have to start over from step 1.
8. Looks like a cheap watch. Made of plastic with a sheet metal cover.

Watch looks nice. Battery life is great so far, 2 weeks. Health monitors are bad. Heartbeat monitor is so inaccurate it's not worth having.
