Very useful until you ask for HR adjustment
I was happy with my HR monitor from myzone until I asked support to lower my maximum HR. I was working out too hard and not recovering from the workout in 24 hours. Instead they raised it to 194. I'm a 60 year old woman. I think I would be the best person to calculate how high my HR should go, not some tech support person on the other side of the world.
