I've got an F7 that works with Flowlink pad. Works like a charm, but the CS300 Weblink that works on sound (sounds like a 1998 modem on helium) sucks. First ever Polar I had I never downloaded a thing for that reason. When I bought CS300 I ASSUMED it was Flowlink. Dumb me for not checking. It's a super watch and HR monitor. But Discovery Vitality only allows you to link Polar. Wish they would accept Runkeeper or Endomundo. RCX5 looking good to me.
