Query: Good features, poor execution

The watch looks great and has all the features I wanted in a sleek size (for the features it has at least). All the features seemed to work as advertised, though the temperature only works well when you aren't wearing the watch.I had two reasons for the low review. First, the user interface seems overly complicated. I rarely could figure out how to do anything other then switch screens on this watch without the manual. I've owned other feature full watches before and this was the hardest to use. Second, the band sucks. The first two years I had it the band broke twice and it uses a custom band so you have to pay $$ to get another one, just to have it break again. After the 2nd time it broke I threw it to the back of the drawer in digest. I will not put more money into it.
