Cadence sensor Bluetooth® Smart is rated 2.7 out of 5 by 3.
Rated 2 out of 5 by from Needs to be cut in two to change the battery I use mine on a Lightning Cycle Dynamics P-38 recumbent with Map My Ride...I stuck a stack of three 12x3mm neodymium magnets on my left pedal and angled the sensor about 45 degrees to bridge the gap... A bit weird looking and it does offer function over fashion. Needs to be cut in two to change the battery every few years - There are videos on youtube of folks doing this. Ideally, there would be a hatch to enable non-destructive battery replacement rather than encouraging folks to throw the $50 unit in the trash/e-waste when it just needs a battery.

Rated 5 out of 5 by from Easy to install and works well Installed on my bike in minutes and works great with my V800. Had no problems syncing with my devices following the provided instructions. The only thing I would improve is the tape that comes with the magnet could be stickier.
