Just an awesome product! I have never written a review on amazon before, but I had to with this watch!!! It does get a bit finicky when trying to update from my room, so every few days I just set it in the backyard and manually update it and charge it as well. I didn't even get the watch from amazon actually, but it is so good I wanted to push others for this watch! I have the 5600e for work, and the J is my "nice weekend watch" hahaha. A+ on fit, finish, and quality!
