Bound easily to a Lezyne Super Pro GPS unit. In fact it works better than the Lezyne sensor's. Except that the GPS doesn't detect the battery charge. But it was spotty with the Lezyne sensors anyway. Even when new. I've only used the Garmin sensors a couple of times. But so far I'm very satisfied that they even work with the Lezyne GPS. The Lezyne sensors are really cheaply made and suck the battery down really fast. Even when not being used. The quality of the Garmin sensors is far superior. And the price isn't much more than the Lezyne sensors. So far I'm very satisfied with the Garmin sensors. I may have to buy another set.
These guys are easy to install (much better than the previous generation) and work well. Connecting to my Edge 530 was easy and I don't notice any dropouts. The rubber bands seem sturdy and battery life is extremely good. The cadence sensor is essential if you're a data nerd. The speed sensor may not be so important, because the Edge also tracks speed. However, some online reviews suggest speed is measured more accurately by the sensor. You also need a speed sensor if you use an indoor trainer, or if you ride in an area where GPS frequently drops out due to buildings, trees, etc. I have a couple of speed sensors (one for each wheelset) -- they're a pretty cheap add-on if purchased in the bundle with the cadence sensor.
I use this these sensors on both my full suspension mountain bike and my road bike. I also connect them to both my Garmin edge 820 and my Garmin Vivoactive Watch. Set up was really easy in both cases, and I haven't had an issue since.
The old cadence sensor required a magnet affixed to the crank and a transmitting unit located on the lower frame arm. Both required tight tolerances and easily could get out of alignment due to bumps or whatever. The new unit attaches to the left crank arm and can't get out of alignment. The speed sensor worked off the real wheel magnet and cadence/speed sensor. Again, the unit required tight tolerances and easily could be dislodged and require adjustment. The new speed sensor is great as it attaches to either hub and requires no further adjustment. Both units pair well with my Garmin Edge 500.
The moving sensor is great for if you are riding in areas where the GPS can be spotty. I enjoy being able to view my cadence and having my avg cadence at the end of a ride. Even got one for my girlfriend who now loves checking her cadence.
Great for tracking rides with a compatible device - I use a Garmin watch paired with these. It's good especially to get a sense for how cadence is and how it correlates with heart rate and things of that nature. Simple, reasonably-priced bit of cycling gear :)
