It is more expensive than some simple screen protector but also brings more power. It is a really robust Glass- "film" that is applied on 'display and of course protects you against mechanical impacts better than a simple film. Supplied with an alcohol swab, a microfiber cloth and a anti-static cloth this to really bring down every speck of dust from the display. In my case, the application has to run at all. I was allowed to test this product for free! Thanks
