Polar F6 does what it says

I got the F6 to monitor my heart rate and aid in burning calories. Since the watch uses your own heart rate, weight, height, age, and various other information to compute your calories burned you get a much more accurate picture. I found that my treadmill, which tells me the number of calories burned, was nearly 200 calories higher than what I was actually burning per the F6. This is extremely helpful as I aim for a certain amount of calories burned per week and need to be as accurate as I can. The watch is also user friendly, if you just go over the manual first! I looked the manual up online and knew how to use the watch before it even came. It has functioned perfectly for me both in doors and outside in 20 degree weather with four layers of clothing on. I use a treadmill as well as various DVD's and get consistant readouts each time. Knowing your heart rate while you workout can keep you from working longer than you need to get the results you want. By staying in the zone that you set up before each workout you get more out of your workout. If you are looking for a simple watch that can help you stay on track for your fitness goals then I would recommend the F6. I love this watch and would buy it again.
