Wahoo RPM Cadence Sensor is rated 3.8 out of 5 by 97.
Rated 3 out of 5 by from Works great ... when it works I was excited to find this product to use on my new spin bike to track cadence. Out of the box I could not get it to work. Emailed support, and in addition to trying a new battery was given a list of things to try (restart my phone, etc.). The minute I put the new battery in, the flashing light appeared and I was set. (So why even insert the battery in the product? Either send without a battery or include it separately). I used it to spin twice in three days and it was great, I was stoked. Two days later and less than a week after replacing the original battery, I go to spin and the sensor isn't connecting. Try a new battery and we are back to the blinking light and it's ready for use. I have my sensor laying in two parts with the battery not installed in hopes of getting more than a week out of one battery, otherwise I'd be better off paying for a spin CLASS than replacing a battery every week. SERIOUSLY Wahoo, this product is on the verge of being SO GOOD but this battery thing has to be fixed. An on/off switch would be great. Instructions on removing the battery between uses (as much as pain that is?) or would 'forgetting the sensor' on the app work too? Not sure and I'm taking no chances but my excitement for this has waned with this battery issue we are ALL having. PLEASE FIX

Rated 5 out of 5 by from Works with Strava, iPhone & Apple Watch Setup was a little rocky, with instructions hidden away in the website, and pairing with Strava app on iPhone took a few tries. It pairs with Strava as Speed & Cadence, rather than just Cadence, but works. Once the sensor is paired with Strava on the iPhone, starting Strava from Apple Watch captures cadence seamlessly. Didn't have clearance to mount on the inside of the crank arm, but adhesive mount on the outward-facing non-drive arm near bottom bracket works well.

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.
