The product complies with the description, multi-page manual, exceptional protection setting, shame we intended it in the trash, in short, you know that you are in the world of luxury, since this Polar belt, you pay 4x the price of its equivalent Decathlon that is more compatible with my H7 ... But here, Polar is to sports what Apple is bobos, so you put the price. Finally, if I had known before the Decathlon was 4x cheaper, and worked for my perf H7, polar would have remained at the store!
