I purchased a Wahoo Blue SC last January and it worked fine when my bike was on the trainer. When I took the bike on the road this spring the sensor began working intermittently, then quit completely. I replaced the battery and have adjusted and readjusted but at best, it works for a few minutes then quits again.

I'm looking for a reliable cadence sensor (with or without speed sensor) that will work with Ride with GPS on an android phone. Any recommendations?
