I feel like I'm relatively tech savvy, but this watch is very surprisingly not very user friendly.  The setup was somewhat frustrating and didn't have the ease of functionality that I anticipated.  I was looking for a really simple watch just to be used while running, but I'm not sure if I'll actually use it at all.  It seems durable enough for the use I intended for it, but having to fiddle with it so much for basic functions is pretty disappointing.
