Waste of Money!
I hardly ever review products but this strap was a waste of money and I feel that others should be warned. It worked for about 2 weeks. After that it started to drop the heart rate signal during every workout. The rubber backing that holds the sensors is peeling off the strap on both ends. I have replaced all of the batteries to make sure that something else on the watch wasn't effecting the signal. This is the first and last time I buy anything but a polar replacement strap (which by the way lasts over a year with literally everyday use and washing)! If I had saved the box, I would have returned it!
