Summary: The unit connected flawlessly to my Garmin 910XT. I had to raised the sensor leg in order to detect the wheel magnet for the speed, but it was really easy to do with screw driver. Garmin provided two different bottom feet depending on the shape of your frame, which made the installation a breeze. Overall, battery, connectivity, and accuracy of the unit have been flawless!
Summary: Quality product... now the 6th I've purchased for all our bikes. The design is low-profile, lightweight, and adjustable. It is very quick and easy to set up, and works flawlessly with our ant+ enabled watches (Garmin 910s) to see bicycle speed and cadence. I'd definitely recommend this product to anyone who's looking for more data on their bike rides.
Summary: Easy installation, quick connection, continuous data transfer. It is a training partner you should have. This was for my second bike and I'm using Garmin Edge 800. Just select bike 1 or 2 and go.
Summary: This sensor was easy to install, and the small LED on the unit made it simple to insure the wheel and pedal magnets were aligned with the sensor. It has only been used on a trainer indoors so far, but the bike has been moved a few times without changing the alignment of the sensor.
