Unreliable, cheaply made, poor design
I purchased this heart rate monitor and it has been collecting dust on my shelf ever since. It's completely unreliable as it rarely picks up my heartrate for any extended period of time, even after wetting the electrodes. The electrodes are tiny compared with any Polar brand model. Obviously, not much $ and thought when into the monitor's design. The watch is huge and ugly. For this amount of money, you would do much better buying a Polar FS1 which is just about the same price. That's what I did and I am thrilled with the Polar monitor!
