Blue SC Speed and Cadence Sensor is rated 4.3 out of 5 by 155.
Rated 1 out of 5 by from Still trying to get it to work. I'd love to be able to tell other prospective buyers that my recently purchased Blue SC is working but so far, I can't tell. The only indication that I am seeing while using the Wahoo fitness app is "I'm Working" shown on the RFLTK display. I don't see my heart rate from the Blue HRM or the speed/cadence from the Blue SC. Maybe I'm doing something wrong.

Rated 5 out of 5 by from Astonishing! I was very sceptic when I decided to purchase the product to be honest. Previously I was using some low-budget, Chinese bike computer with cadence sensor (cable) and it was running perfectly. Then I decided to purchase a Bluetooth kit from one of the market leading brands and... catastrophy! I couldn't even let it communicate with anyof my Android devices. Then I read some reviews of the products similar to Blue SC and I was almost sure it won't work, but I decided to give Wahoo a chance. And you know what- it is my best electronic bike accessory I've bought so far. Once it is paired with the smartphone (Huawei P9) it connects immediately as soon as you get closer to your bike and moves it. It runs reliably- I've made some 700km so far in good as well as severe conditions (-5 degrees Celsius and heavy rains) and it never failed even for a second. It doesn't react as fast as cable sensors of course (due to BT response), but it is precise and reliable. I recommend it to everybody that cares about cadence and to be honest- it is one of the key features you need while biking. All the rest (distance, speed, pace, etc.) you can get even from GPS via dedicated app, but cadence (plus HR) is the key to effective training and Blue SC is the best choice!

Rated 2 out of 5 by from Kind of a pain.. I have two issues. One is that the alignment is really finicky and I have to fiddle with the position before every ride. The second is that I have lost several magnets - I ultimately ended up purchasing a 3rd party magnet from eBay that I secured to the crankshaft with a zip-tie, and that problem was solved. While I haven't tried them yet, the RPM sensors seem like a more solid only because they won't have these issues.

Rated 1 out of 5 by from Easy to Install and Use! Performs great. Installation was a snap and set up easier. Both sensors quickly synced up with my iPhone app and away I went. Have had it for over a month and no issues. I wish all electronic gadgets were this easy. Highly recommend!

Rated 5 out of 5 by from Exactly what I wanted I purchased the Blue SC Speed and Cadence sensor for my indoor bike trainer. Installation was simple and 10 minutes after I started I was complete and using the app. I use my indoor bike trainer for cardio day v/s running or the dreaded treadmill. The app is awesome and the best part is being able to easily email the results so i can log it with my other workout stats. Wished i had found this product long ago!
