The Garmin HR sensor that came with my Edge bundle has a dead battery after just 6 months, and the tiny screws on the battery compartment are seized solid. Even with the correct sized screwdriver I am unable to change the battery, so the sensor is useless ....NOT HAPPY GARMIN !
So, I am looking at the Magene H64 HR sensor as a replacement at less than a third of the Garmin price. It is a dual ANT+/BT unit just like the original Garmin, so it "should" connect properly, but I would just like to check ...anybody using one with their Garmin head unit ? I see that Magene had the sense to use a more robust "coin in the slot" type of cover to replace the battery unlike garmin's 4 tiny little screws !
