Wahoo RPM Cadence Sensor is rated 4.077922077922078 out of 5 by 77.
Rated 1 out of 5 by from Battery Keeps Dying The sensor came with a dead battery. I asked for a new battery twice and received 0. I bought new batteries and after each ride, the battery goes dead when I go the next day. Kind of disappointing.

Rated 1 out of 5 by from Not Very Accurate I bought this a few weeks ago and attached it to the crank arm on my bike with the tie wraps and silicone case. I have done several rides but the cadence is all over the place, my averages are down and my max cadences are through the roof (my legs can't spin that fast) so it will be going back to the shop for a refund as it is unuseable....shame really

Rated 5 out of 5 by from Great product! Good quality product, tiny and light... connects incredibly easily and provides good cadence data. Very good workout analysis when combined with data from HRM.

Rated 5 out of 5 by from Great product at a good price The cadence sensor works like a charm and was easy ti install. I wanted a dedicated cadence sensor not a pod for my Suunto Ambit 2 watch so I could get GPS data for speed.

Rated 1 out of 5 by from Not happy I bought this from you and it did not work, so i sent it back to the supplier. Hoping to get a refund. I have not heard anything about a refund. I phoned the supplier and he says that they have not recieved it. So looks like i lost my money. So not happy.

Rated 5 out of 5 by from Incredible Cadence Sensor Incredible Cadence sensor. Finally I can ditch the bike computer and use my phone instead.

Rated 4 out of 5 by from Needed new battery Good device, but initially unreliable connection. There is no way to turn device off so I think battery gets worn out by motion during shipping. Easy and cheap to replace battery, then performed well. Would prob be better if shipped without battery installed for user to insert supplied battery on receipt.

Rated 3 out of 5 by from Good but not consistent I received this as part of my PAIN CAVE bundle. The RPM device is good but I find that sometimes when I'm pedaling pretty fast it will still read around 47-52 RPMs and or drop out for a minute.
