Review on 🚴 XOSS G+ GPS Bike Computer with Bluetooth ANT+ Connectivity, Wireless Bicycle Speedometer Odometer and LCD Display, Waterproof MTB Tracker Ideal for All Bikes including Electric Bikes (Supports XOSS APP) by Marc Sortijas

I bought 3 of these units and once set up they work fine. All 3 had problems syncing with GPS. It often required connecting and disconnecting the app, syncing the device and waiting for the GPS to find satellites. Once the initial GPS sync has been achieved all 3 devices work fine. I love that I don't have to attach a magnetic sensor to the bike to measure distance - just install XOSS and go. I have an XOSS connection with my Polar heart rate sensor and it works without any problems. If you can connect a GPS device, that's great. Tying him up was a pain.
