Bests & Worsts Reviews from Amazon

Good: - Works as advertised - Easy to setup - Rugged and well constructed Bad: - Wrist watch does not start receiving heart rate unless you are sweating at lot/apply a lot of water on the strap and your chest - In a gym setting, there seems to be interference from electrical equipment (treadmills, etc) and the monitor works intermittently - If there are other users w/ heart-rate monitors in the vicinity, their readings and my readings overlap causing some amount of confusion
