Anyone have a Polar F4 Heart Rate Monitor??

StrengthInPain

Anyone have a polar heart rate monitor and happen to have, and be willing to give me a copy of, the receipt or proof of purchase? I bought a HRM about a year ago on eBay, and I thought just the battery had died, but I took it to get the battery replaced and the guy said that there's something wrong with the watch itself, and I should send it to Polar for them to fix. Polar will only fix it if I have a receipt. I think their warranty is 2 years. Obviously, since i bought it on eBay, I don't have an actual receipt. So i thought i'd take a shot, if anyone has a receipt that is within warranty, and wants to help me out to get my HRM fixed. Thanks!
