Bests & Worsts Reviews from Amazon

You get what you pay for, right? Right. I've wanted a strapless heart rate monitor for a while now, but could never justify the expense; I'm a regular gym-goer, but not a serious athlete. Once Groupon featured it for $20, I jumped! Resting, the heart rate monitor works well and seems to be very accurate. Whilst exercising in a fashion that gets your heart pumping, fahget about it! I've tried different pressure, wiping my fingers from moisture and holding them on the sensors for various amounts of time. Most of the time it won't give me a reading, even after 10 full seconds, rendering the device nearly useless (for what I wanted it for). Ultimately, it's become a $20 stop watch that doesn't fit very well. Invest in something nicer if you truly need performance!
