Blue SC Speed and Cadence Sensor is rated 4.4 out of 5 by 141.
Rated 2 out of 5 by from Works well, but soft polymers failed constantly. I bought this a bit more than a year ago. It did work well, although it took a lot of fiddling to get the cadence sensor to work consistently. Biggest issue is that the plastic straps broke frequently, so I've spent several evenings trying to find fallen magnets or event trying to recover the sensor itself from a ditch after it popped off of the chainstay. I eventually had to switch to an Elemnt and a different cadence sensor. I did stay with wahoo though because it had worked well for me.

Rated 5 out of 5 by from Easy to set up, works right away! Was given the BlueSC for Christmas and it's great! Takes a couple minutes to get the placement just right on the frame, but once secured, it worked perfectly. Connected immediately to iPhone via the Wahoo app, and then linked to Zwift on iPad. Makes my classic indoor trainer a lot more enjoyable and look forward to getting this out on the road in the spring! Thanks Wahoo team - great product.

Rated 5 out of 5 by from Dead simple, no problems I'd seen several reviews where people complained about accuracy. Well, I've been using mine for a couple of months now and I have found: 1. super simple to install and set up 2. very consistent readings. Nothing indicates that readings fluctuate 3. seems very accurate 4. pairs easily with other apps So, there doesn't seem to be anything systemically wrong with this unit. Maybe its the luck of the draw. But my experience has been nothing but positive. I would not hesitate to recommend or to purchase again.

Rated 5 out of 5 by from Worked First Time! This is super easy to install, setup, and test! I was receiving speed and cadence numbers after a minor "tilt" of the unit. Remember to set the wheel diameter to ensure speed accuracy! I finally have cadence and can't wait to log some miles on the trainer this week!

Rated 1 out of 5 by from Cadence sensor fails too much The big advantage of this sensor is the ability to connect to ANT+ and Bluetooth 4.0 devices and being integrated cadence and speed sensor. the big disandvantage is that cadence is measured only if the magnet is really close to sensor and frequently on the road cadence info is lost, although it is very tight. Other disadvantage is the high battery consumption, i have this for 3 weeks and 2 batteries have been depleted. When it works it measures the information correctly.

Rated 5 out of 5 by from Awesome! Bought this to connect my tacx turbo trainer up with sufferfest app. Absolutely love it, super easy to set up and connects with the app to give Virtual Power as well as cadence readings. Would recommend to everyone looking to get more out of their training sessions.

Rated 4 out of 5 by from Great product, recognized by smartphone and fenix3 fits perfect on a carbon bike with large frame (you need to use the collars and not the rubber ring). Works perfect with Bluetooth with Garmin fenix3 and smartphone. (fenix3 will calculate the radius based on GPS measurements)
