I have a Samsung gear and I can see why the returns. Mainly I am sure because of the ill fitting band. I have a rather normal wrist and the band is too small and stiff, does not mold to the wrist. I needed an extra hole or so. I have kept it and jury rigged it so I get by, but that would be my only complaint. The pairing and software works well. No problem with keeping messages alive. Sound commands work well, with or without teeth in.
My only real problem is I haven't worn a watch for years. There are just oodles of places other than your wrist to see the time, the car, the stove, the microwave, the TV, the computer, banks train stations and airports, et cetera. et cetera. et cetera. (with apologies to the late Yul Brynner)
