The films are easy to apply and work without adhesive. They fit perfectly! Best places they at one edge of the display glass and then remove them with a cloth or a plastic card on the display. Just drauflegen and press does not work because otherwise air bubbles under the film, which then interfere with the image evaluation massively. The film very well protected against scratching the display by zippers, buttons ect. to clothing (if you let them hang in front of the abdomen). Against rough blows or even a fall of the camera, this film does not protect natural. With a Bride camera so quality should afford these films, so you can still recognize what in a few years on the display. I'm very satisfied.
