Wahoo RPM Speed Sensor is rated 3.9 out of 5 by 33.
Rated 3 out of 5 by from Works ok Bought this thinking it might be more accurate than the GPS but I'm not realty sure it's made any difference

Rated 3 out of 5 by from rubber band is way to short If you use a hub dynamo (in my case a have son dynamo) the rubber band is way to short and is useless in my case. It would be nice to point this out in the product description or they would add a second, longer rubber band to the product, like garmin is doing with their sensors.

Rated 5 out of 5 by from Awesome I wanted to remove the clutter from my road bike and manage everything from a single display, an iPhone mounted on my handlebars. I updated all sensors with Wahoo products and couldn't be more pleased. The RPM and Speed sensors connect flawlessly with my iPhone every time. Same for the HR monitor. So, there's really nothing more to say about the sensors. The real awesomeness is in the app. Wahoo's Fitness Tracker is by far the best. The numbers are large and easy to read. Without squinting or looking at separate screens, I can see everything I need to get the max out of my ride. It would be nice to be able to load a Map My Ride-style route. It would also be great to access the data from a PC or Mac. Maybe there's a way to do these things that I haven't discovered yet.

Rated 1 out of 5 by from Does not fit my Old Super Record Hubs. Bought this and it does not fit my hubs. Product is not universal. The hub diameter has to be rather large for the mount to work. Very disappointing.

Rated 5 out of 5 by from Simple and good I bought this to replace my garmin speed sensor of the same type- it had been acting up and several computers struggled to pick it up. The Wahoo speed sensor is easy to install, and hasn't done anything other than work how it should. Great sensor.

Rated 5 out of 5 by from Works well on Rollers Have not checked accuracy on the road, but for winter training it has been a great addition. Still will not update with Wahoo Utility (showing "failed to respond to test" or some such thing). For $40, its was well worth the investment.

Rated 4 out of 5 by from Works as promised This did not work at first, it turns out the battery that it was shipped with was dead. Once I replaced it the unit worked fine. It does take some time to connect with the software, but I assume that is a SW issue.
