Nice magnet, good measurements, I have been using it flawlessly for 1 year. I recommend it! The only downside: To light up the screen, you press a button. But the screen stays lit for 5 seconds. But you can't do it continuously. So at night, you pray for the road to have many streetlights to see.

Unfortunately, the magnet does not screw well, resulting in it falling off. The only solution is to replace it with another magnet.

I have been using it for a year and it is excellent in everything, it has never disappointed me, in rain, at night (the lighting is perfect), in the mountains with vibrations, it has not suffered anything
