Buying Heart Rate Ring

I tried to use it with my stationary bike and unfortunately it doesn't work. It will not give you consistent readings when your heartbeat rises, so it's useless while you're exercising. It's now sitting at the bottom of my trash bin. The only good thing about buying it was that I could keep the two new CR2032 batteries for other gadgets -- pretty expensive batteries these two. Avoid it at all costs.Get more detail about Heart Rate Ring.
