    First off, fhe fit was spot on with the sizing rings. Functions as intended I just wish I got the expected battery life they advertised. Not the end of the world since it charges quicker than expected.

    Bought as a gift, she has enjoyed the metric tracking compared to the Apple Watch. Probably would never be a true replacement for the watch though as its less useful for working out.
