Review on High-Speed DC12V Digital LCD Motorcycle Speedometer, Vibrant LCD Motorbike Odometer Tachometer Speed Gauge Sensor by Peter Tennant

Odometer not working. The speedometer is set up correctly and matches the GPS speedometer on my phone, so no. The odometer will reset and display a random, incorrect mileage. Here's what has happened so far: I took the first ride, drove about 4 miles and parked for 2. The next day I start the engine and it shows 3 miles. Then I drove about 14 miles and the odometer only showed 12 miles. When I went to start the bike the next day, the odometer read 7 miles; Driven 3 miles, now it reads 4 miles. While this is the only issue I have had with this speedometer, it is a BIG one. I think I have a faulty speedometer and would like to update my review if the seller replaces the unit.
