Great watch for running and keeping track of multitudes of information. The only thing that keeps me from giving this product five stars is the crappy IrDA USB device that's included. It only worked sporadically and the watch had to be pressed right up to the USB device. I ended up buying a Startech IrDA adapter for $21, which works great.
