Review on 🚴 MOOFIT Bluetooth/ANT+ Speed and Cadence Sensor for Cycling - Wireless Bike Cadence Sensor for iPhone, Android, and Bike Computers by Nelson Calafell

They worked great for a couple of rides on the Zwift and then suddenly stopped transmitting the Bluetooth signal. They have previously worked on this computer (Macbook Pro), tried restarting and even put in new batteries, but still nothing. Searching the web for Revain, I see that there are no sites that support them, no warranty information on the Revain pages, nothing. If you're buying cadence or speed sensors, spend the extra money and buy from Wahoo; they will at least post information about their guarantee somewhere. Another note: If you are using cadence/speed sensors for Zwift, be aware that "Zwift Power" is fake before you buy. I recently purchased a Wahoo Kickr Core (which always emits a strong Bluetooth signal) and compared my efforts on the same workout. These sensors required me to pedal at 120 rpm to hit 250 watts, but the smart trainer that adjusts resistance was MUCH more difficult to manage. There was a big difference between the effort on each, although Zwift's assessment for the speed/cadence sensor said it was the same as the Wahoo - it wasn't. If you're into Zwift, get a smart trainer instead that gives you more precise power. June 2021: I was recently contacted by this seller. Not only did they offer no guarantee for the product, but they also offered to pay me to have this review removed. Potential buyers should know this before buying.
