The larger the machine, the more difficult it is well to apply a protective film. It mus be very patient, have a 100% fine motor skills and a sterile area without dust booze. I gave up after about an hour and dispose of the foil.
Apart from this, the material quality is very good, the screen protectors for protective film (there is finally also bumper protection for your car, why not?) Well placed and easy to erntfernen.
