I like everything about this watch except perhaps the battery life. It seems to last about a day and a half, maybe two days. It charges quickly though so it's no big deal. It has so many great features. My first watch (different kind) failed after my first day working in the wood shop. I'm not crazy about the app you are supposed to use with this watch but I'm sure there are others out there that are better. I keep up with the metrics by other means and just use the watch to gather data. I'd recommend it and even buy it again if this one should ever fail.
