My sister-in-laws both had this watch and I wanted it sooo bad so my cool mother-in-law got me one for my birthday! K-Coolest watch EVER!!!!
It has a heartrate monitor that's attached to it and when you exercise it tells you your heart rate, how many calories you've burned and how long you were in your target heart rate/fat burning zone. I'm telling you, it's great if you exercise! If I was Oprah, I'd buy ya'll one ;)
