Review on 🚴 POSMA D3 GPS Cycling Bike Computer Speedometer Odometer with Navigation and ANT+ Support - Strava and MapMyRide Compatible (BHR20 Heart Rate Monitor and BCB20 Speed/Cadence Sensor Bundle Option Available) by Debra Decou

The hardware is of good quality, but there are a number of issues with the firmware.1. If you delete a working file from your PC (Windows 10) while connected via USB, the file will disappear but the disk space will not become free disk space again. Therefore, you can only delete old files from the file menu on the device.2. The user manual is not clear. Example Setting the initial height, options other than "manual" do not make sense.3. Trouble uploading trips to Strava.4. Lots of usability issues. Still on the device software / firmware v 0.015. No website for support and updates6. The slope of the road reacts very slowly to changes.
