Just awesome. So simple to install. No magnets, just the sensor easily attached to your crank by one of three rubber bands of varying lengths. The CR2032 battery is long-lasting and easily replaceable. This works with ANT+ and Bluetooth so should pair with just about anything. I use it with a Garmin Edge 500. It's about $40.
