What good about this watch/band is that they weren't trying to do too much.
Other smart watches are trying to be like a small phone on your wrist.
This is a sports band which can do extra non-complicated things.
I like the Fitbit watches/bands that they just announced. Looks better than this one. I'll wait for comparison for battery and heart rate monitor (calorie counter) before I decide.
Right now I have Fitbit Flex and I like it (although no watch is bad).
