Review on Lixada 4g Ultra-Small Wireless BT & ANT+ Bike Cadence Sensor: IPX7 Waterproof Speedometer & Computer by Reginald Ward

Ordered on the 7th and received on the 24th. Came straight from China. No reference, as in all other reviews of similar items. Came with a spare battery and a few extra mounting washers for double sided tape and zip ties. Just shake the sensor and it will instantly pair with my Garmin Vivoactive 3. Once installed, spin the pedals to wake it up and it will connect. I'm not sure if there was an Ant+ or Bluetooth connection as the Vivoactive 3 has both. Ridden for 53 minutes, cadence was reliable with no loss of connection. I have two peaks in the cadence chart but overall it was very stable. Although the assembly technique is cheap, it is similar to others. Time will tell if it holds up. A very affordable Garmin alternative and perfect for intermediate to serious bikers. Recommend.
