  • Rated 4 out of 5 stars

    Good value, bad battery

    First time ever buying a smart watch, and I'm pleasantly surprised at how well it fits (I apparently have gorilla wrists) and I love the different gizmos and such it has. My only two gripes are the battery (which honestly this may just be because I bought it used) and the fact that it likes to count steps whilst I'm driving.
