Blue SC Speed and Cadence Sensor is rated 4.375 out of 5 by 112.
Rated 4 out of 5 by from Reliable device Works as advertised. I had issues with connecting the device to my bike due to the shape of the chain stay. Ended up mounting it upside down. Also, the wheel magnet does not fit the bladed spokes. I tried using a different magnet as recommended by Wahoo, but the sensor could not detect it. I have since changed wheels, and the original magnet is fine. Make sure to zip tie the sensor to the chain stay, as the rubber band is not secure. Once I sorted out these issues, I have not had to make any changes, and the device works fine. It always fires right up, and never loses communication.

Rated 5 out of 5 by from Excellant Sensors I purchased the Wahoo heart sensor and speed and cadence sensor this past spring to work with Map My Ride and Ride Buddy apps on my iPhone for my rides. I ride 2 to 4 times a week with a long ride on weekends, a +/-100 miles/week total, and both sensors have performed flawlessly. I can monitor and record all of the information I need on a ride and easily chart overall fitness progress and know when to push and when to take it easy. These sensors provide a way to see effort and progress without the large expense of a power monitoring set up of some sort. Great product, well designed, and very useful for heart rate monitor training. Before Wahoo, I add different sensors and two different displays to monitor speed and cadence, and heart rate information; Wahoo put it all on one device/display.

Rated 1 out of 5 by from Does not work - disappointed with the product Brand new out of the box. Installed it and can hear the sensors for Speed and Cadence clicking when wheel and crank are turning. Setup on my iPhone 6s Plus went as shown in the video. The sensor shows speed and cadence but the software does not display the speed and the cadence is 175. I've wasted 2 hours trying to make this work. Total waste of time and I'm disappointed with the product. Moreover the "Support" tab does not function on the website. I have half a mind to take the kicker and HR monitor and all the goodies back to the store and wait until the product quality improves.

Rated 5 out of 5 by from Works like all the others, mount sets it apart. This sensor is really the same as all the others I have used, except its mounting. I like that I can move this sensor between my bikes easily. I frequently switch between my road race, crit, and TT bike, so the rubber strap makes it a notch above for me.

Rated 5 out of 5 by from Perfectly simplistic The blue sc device is genius in design and function. The manner in which it integrates with the rflkt computer and transfers between my road and TT bikes is everything we want today, in a world of overly complex, often proprietary bike products that frustrate consumers, all wahoo products play nicely. The accuracy and simplicity of installation/pairing gets you on the bike fast and without an elevated heart rate!!! Bravo

Rated 1 out of 5 by from Don't recommend It worked the first three times I used it and then stopped showing my cadence and speed in the "workout" part of the Wahoo app. Oddly enough the lights flash at first and the "sensor" screen shows it is connected, but when I press "start" on the workout it does not connect. Very disappointed and irritated considering how much time I've wasted trying to get this to work. In addition, the sensor tends to slip on my small chainstays. It would've been helpful if Wahoo had included a thicker bracket so I wouldn't have to fiddle with this constantly.

Rated 1 out of 5 by from Terrible sensor Bought Blue SC sensor to use with my Cyclometer app. The sensor is a piece of junk, stopping intermittently and unpredictably so that my Cyclometer app would stop and say "... An app is trying to access your program ..." and would stop the program from running until you say Ok and then restart the program. After the sensor stopped my program three (3) times and thereby losing all data, I literally ripped the piece of junk off my Trek Madone 7S and literally threw the piece of junk into the Pacific Ocean as I was riding along HWY 1. I would NEVER buy the sensor again, NEVER. I hated this piece of junk and was thrilled to throw the device into the ocean! Do nor buy this sensor unless you want to lose data and have a sensor that intermittently works!

Rated 5 out of 5 by from Just works as it should! Purchased another brand of Bluetooth Speed/Cadence Sensor before this one. It never worked reliably. It would always disconnect/reconnect. Got the Wahoo, set it up and voila! Worked perfectly on the first go. I like the fact that it is Ant+ for my cycle computer and Bluetooth for my phone. And the option to upgrade the firmware is great. If Wahoo finds a bug/compatibility problem they can fix it.
