Garmin ANT+ HRM Heart Rate Monitor Chest Strap

X2 Garmin ant heart rate monitors and belts, with ant dongle and micro usb cable to attach to phone or dongle straight to laptop etc... brought this lot for me and my friend for training on the tacx app, but I didn't realise it only supports Bluetooth so there's no use to me, the one ending in 70 just had a new battery, the two heart rate pictures show them working perfectly, it's a shame as ant is better than Bluetooth but there you go, cost me u00A375 for the lot so bargain uD83DuDE42 these are fully adjustable in size carnt seem to change M/XL
