Title: Stops working accurately
Review: I've owned two of these watches and both of them stopped reading my heart rate accurately within a few months of daily use. While running it will start out giving an accurate reading, then start jumping around, giving me an impossibly high (151 at a slow jog) or low reading (71 while running uphill) or it will jump from an extremely low to an extremely high heart rate (51 to 160) in a second, a virtually impossible reading. It's maddening. For some reason, I do not have this problem while working out indoors at the gym. Only when running outside. It's too bad because it's easy to use. But what's the point of a heart rate monitor that reads everything but your heart rate.
