I had an issue the first few days with the Sport blue band making my wrist red and itchy. On a hunch, I took the band off the watch and ran both pieces under running watch, rubbing with my hands. I dried them off and put it back together. No more irritation! There must have been some residual chemicals from the manufacturing process, probably some kind of mold-release compound. While the major issue with it is now resolved, I still don't know if I'm keeping it. There are some neat things, like navigation. When using the phone, you basically need to listen to the phone. With the watch, you don't. You can listen to your radio and you get tapped when you need to make a turn. I don't remember this being advertised, but you can do music two ways on the watch. You can install music on it and use bluetooth headphones OR you can just use the music app to control the playing of music on your phone. Star Walk has neat watch add-on if your an astronomy buff. Still, a lot of money for things that are just 'neat', but not necessary.
