Title: Polar Heart Monitor
Review: I used my Polar F4 consistently for 2-3 weeks before I ever had any trouble with it. Now I can't get it to pick up a heart rate, and if it does, it isn't even close to correct. I have tried all of the trouble shooting techniques, and nothing has worked. I will be sending this back to my great disappointment. I will probably buy a different one, but I wouldn't recommend this one to anyone.
