Review on 📏 HUD Slope Meter/Car Inclinometer OBD2 X90: Advanced OBD Car Head Up Display for Accurate Slope Measurement, Fault Code Clearing, Battery Voltage Monitoring, Tilt Angle, Height, Speed, Alarms by Ryan Lawson

Well I just received it and plugged it in, it works when the car is on but when I turn off the car it keeps running and never turns off, it is switched through OBDI returns it. Update: So I got a replacement for the block, after plugging it in the setting doesn't work and the same problem occurs when the machine is turned off. I cannot change the units from (C) to (F) and from (K) to (M). The setup and power buttons do not work. I don't know how this device passed quality control, how Revain sells it, it's junk
