Review on 🚘 AUTOOL OBD2 Digital Car HUD Speedometer with LCD Display | MPH/KMH, Overspeed Alarm, Auto Voltage Meter, Water Temperature Gauge | Suitable for 12V Petrol & Diesel Vehicles by Keith Alvord

Surprisingly better than I expected. The display is very sharp and clear, the automatic light-sensing feature keeps the display at the right brightness, and for me it does exactly what I wanted: it offers a very easy-to-read digital speedometer that doesn't require me to look away from the road when I'm sitting entirely at the top of my dashboard at the bottom of my windshield. KIA Soul+ 2017. (Short video shows how it is used in my car.)
