I purchased these sensors to replace magnet based Cateye sensors and I couldn't be happier. These Garmin accelerometer based sensors are great. No need to properly align sensors & magnets. Just attach, sync, and go!
I use these in combination with a Garmin Edge 500. As some others have mentioned, the sensors sync up but don't show sensor IDs. The first time I set them up they went fine on my test ride. Then I took my bike to the bike path and they weren't working. After a bit of fiddling and clearing the sensors from my Edge and re-syncing them, they were fine. I haven't had that happen since and its been a few months with 2-3 rides a week.
I do agree that they do take a second or so longer to adjust to changes than my Cateye sensors. If I stop pedaling it takes a second or two to reflect a zero cadence, and when I start spinning up, again, there's a delay. It doesn't matter all that much to me, it's not critical to know the speed/cadence at any given split second.
The speed sensor can be a bit difficult to install. It's almost as if you need to do it one handed. Or maybe my hands are just too big as I can only fit one hand in between the spokes at a time. I guess it depends on your spoke setup as well. I just wouldn't want to swap them between bikes all that often which seems to be one of Garmin's advertising points.
Overall, I just like not having to deal with sensor/magnet alignment and having something come out of alignment during a ride. Such a scenario has happened a few times with the Cateye sensors which required me to stop and make adjustments. I don't foresee that happening with these as they are one piece sensors that rely on movement of the accelerometer rather than a magnet passing the sensor.

Garmin Bike Cadence Sensor
Monitor your pedalling cadence and/or speed as you ride with these easy-to-install wireless sensors.
Simply attach the sensors and ride. With no magnets or other exposed parts to line up, these sensors are easy to install, maintain and move between bikes.
The cadence sensor fastens to any crank arm size and measures pedal strokes per minute so you can get the most out of your training.
The speed sensor attaches to the hub of either wheel and self-calibrates with your edge to give you accurate speed and distance at all times, including indoors on the turbo trainer.
Combine them both and improve your personal best or see where your stand against the pros.

Installation and setup were not a problem for me. However, I felt the speed sensor had a better fit on the front hub. My rear hub (Ksyrium SL, SSC hub) was too narrow for the device to sit flush on the hub barrel. Head unit linked without a problem. No noticeable issues with quality of data. A good upgrade.One note: When turning on the head unit (Edge 500) it seems to sequentially link to the HR monitor, the speed sensor and then the cadence sensor. Each ANT+ device takes a moment to get synched up. Adds a minute or two to the process of getting going. Not really an issue, more an observation.
