Rated 5 out of 5 by from So Easy - No Magnets This sensor is an extension to the Garmin Edge. The Garmin Edge primarily uses GPS to calculate speed. I commute daily to work through woods and the Mt Baker tunnel in Seattle. I get drop-outs, incorrect speed, and missed miles for my commute. It sometimes takes up to a mile for the Garmin Edge to lock in enough satellites to work. With this sensor, I get the best of both worlds. There are no magnets to align or tire diameter to set. The Garmin Edge uses GPS to calibrate the speed sensor. The installation instructions are not very clear. Don't try to setup of the ANT device in your living room, it has to be done outside on your bike. The sensor needs to be moving in a forward director, not just rotating to activate the accelerometer.

Rated 5 out of 5 by from Great accessory I use this in conjunction with my 920xt and the cadence sensor. Especially useful indoors on the computrainer. As mentioned, it helps maintain data in areas where satelites may be hard to get. Easy to attach and set up, easy to pair with 920xt.
