    It does what it says on the tin

    Polar have always produced quality stuff, and the T31 transmitter is no exception. I've been using the S710i watch since 2002. Their maintenance service is expensive for replacing the batteries, so it's cheaper to buy a new strap - especially with Tredz price-match offer. I did try to change the battery, a CR2032, myself with the aid of a YouTube guide, but my effort was a failure, so it had to be a new strap
