Query: Horrible product that didn't work as described

I wanted this to be my entry into heart rate monitors. Well, it did that, because it taught me not to be a cheapskate.The touch feature didn't work at all. Setup was difficult and time consuming. The heart rate monitor was passable, but the calories burned feature was terrible (4 calories burned during a 60 minute spin class?). I returned it for a refund.
