Does anyone have one of these? Pros and cons? What is your experience with it? 24 hr Fitness is having a $100 off sale on them right now, but I would like some opinions. I have a Polar F4, but somehow lost the watch part of it and have been having trouble determining a good calorie level, thought this was help in both areas. Any feedback is appreciated!
