Wahoo RPM Cadence Sensor is rated 3.9 out of 5 by 95.
Rated 1 out of 5 by from Doesn't work I bought this for spinning class and it doesn't work. It works for a few minutes then just shuts off. Don't waste your money buying this.

Rated 1 out of 5 by from disconnects all the time brand new out of the box. arrived with my wahoo kickr, this thing would read rpms, then would constantly disconnect... reconnect.. disconnect.

Rated 1 out of 5 by from Poor out of box experience Out of the box, this had a dead battery. I got it running with 2 2016 batteries (vs. the single dead 2032 battery), but the housing (clamshell design) doesn't close securely. Therefore, the unit won't transmit. I'm going to try and get it replaced.

Rated 2 out of 5 by from Frequent, random incorrect reports of zero cadence This came with my Wahoo Kickr, which otherwise works great. I have it in it's silicon holder, zip tied to my left crank arm. On every ride, it randomly reports zero cadence for a few seconds while power (from Kickr) unit remains constant. This causes Zwift to think I've stopped pedaling - even if it's in the middle of a sprint! I tried moving the end of the extension cable with ANT+ dongle to right under the crank arm but it still is giving me bogus numbers. Bummer.

Rated 1 out of 5 by from Random readings, not stable, very disappointed I have many Wahoo products that are great. Two Kickrs a tickr and other products, they function better than any other brands I have tried. The cadence sensor, not so good. The readings are very random, not steady at all. I have tried adjusting the sensor, I have tried silicone mount, the adhesive mount and different locations only to have consistently inconsistent readings. Disappointed, will need to purchase a replacement.

Rated 5 out of 5 by from Works perfectly for me I've had this item over 2 months. I bought it for two reasons. 1. for my mountain bike which I can't mount a cadence sensor on and 2. when riding on my trainer (my road bike has a cadence sensor in the PT hub and I have a kickr. So I just move the sensor to which shoe I'm riding and it works perfectly. I'm not saying it's 100% accurate since I have no idea and haven't done any scientific tests on it but I will say it correlates to my average cadence on my other devices. For the money and ease of use I think it's great.

Rated 1 out of 5 by from Not consistent I have a dozen or so rides with this sensor on a road bike, zip-tied to the crank arm. The first ride was on the road and was so inconsistent. I gave it the benefit of the doubt and chalked it up to rough roads. I have a KICKR, so I was resigned to keep it for the indoor trainer. The next handful of rides were on the KICKR and it was just as inconsistent, and almost 100% lower, a lot lower. It seems the quicker you spin, the slower the sensor reads. You're better off getting the sensor that uses a magnet if you're concerned with accuracy.
