Having used this watch daily for over 2 weeks now, overall I am impressed with the watch. The dim display that others have mentioned is noticeable, but not really an issue and a worthy trade-off for better battery life in my opinion. My biggest complaint is that the HR monitor is practically useless to me. While running there were HR readings of 170-220 that I knew were wrong, so I ended up buying a Polar heart rate monitor which syncs easily with my watch and suddenly my HR was in the same runs on the same runs Range of 120-140 . Since the built-in heart rate monitor shows the wrong date, I can't use it to track my sleep. The Suunto app is really good and the mileage is accurate compared to a friend's Garmin and Apple watches.
