What can I say... Excellent and reliable. Within two days I found three cars that were not painted, not scratched, etc., which were actually painted. One of them even had a lot of filler in two spots (rear fender and sill). For this amount of money, I did not expect such reliability. Just don't forget to calibrate at the beginning each of the transparent sheets of different thickness that are included in the package. The screen is clear and also has green lighting. Batteries are not included. It also measures aluminum.
