Query: Could Be Good, But Not For Me

All arrived fine and seemed to be all it promised. But it doesn't pick up the senses from my fingertips so is completely useless to me. I plan to send it back and get a wireless Polar model.For the record, I also have an iPod speaker unit that doesn't respond to my fingers. So could be me. Or perhaps isn't for people with smaller fingers.
