QIUTONG GPS Speedometer for Car, Upgraded HD MPH Digital Speedmeter, 2025 New LED Heads Up Display for Cars, Trucks, SUV, Motorcycle with USB C Car Charger Adapter QC 3.0, Black

This is a good speedometer. At first I thought it was broken. There are no buttons or instructions. But once I sat down to look up the product information it connected and has worked f8ne ever since. I’ve got this on my scooter which has no speedometer. I plugged it into an external battery. It’s a little bigger than I thought or need. Using two iPhones as reference the device is accurate. The little sticky pad is very thin.
