Kuaifit Speed & Cadence Cycling Sensor Wireless Bluetooth ANT+ for iPhone, Android, Bike Computers, Headphones - Cycle Bike Triathlon

This was a birthday present for my husband.he was impressed.

Bluetooth connection keeps dropping out, tried with two different devices and same problem. Connection is intermittent when riding

Seems very good not sure of battery life as only had it for 2 weeks but good value

Works very well, have only had it a week and using it on zwift it has worked perfectly well. Looks very similar to the official Garmin one I have on another bike, the benefits of this one being bluetooth so I can use my phone to play/ride zwift.
