Polar F6 Love, love, love this heart monitor!

I'm wearing it as I'm writing this review! It's just amazing how much LESS calories you are actually burning at the gym if you guide yourself by the machines and the standard calculations it gives you; it was an eye opener for me. The other thing I was amazed to discover was how much more calories I burn by actually walking instead of using the treadmill. interesting stuff. This watch is easy to use, I recommend it 100%. =)
