Bought an HRM-Dual together with a Concept2 rower. Ant+ module works fine, but the BT module connects but won't send data. And this was out -of-the-box, Day 1 of ownership. Day 2 of ownership was spent at the local service center, figuring out the issue. Managed to confirm the BT module of their demo unit connects to Polar Beat (connects + transmits heart rate data), while mine connects but does not transmit heart rate data. Regret buying this over the H9 I wanted to buy (wasn't in stock). Had bought the dual anyway thinking I might buy a forerunner in the near future - well, forget that. RMA'ed the dual through the original vendor (service center said they might need weeks to sort out the replacement due to mine not being a local unit), but went ahead and bought a polar. When the dual is replaced, I'll keep it as a spare or sell it. My advice? Avoid this product.
