According to the reviews here, I was afraid to have trouble sticking the film. But: It was very easy and worked immediately with no air bubbles. Sure it helps if you do it with your partner. Importantly, the light sensor and the camera (Galaxy Tab 7 inch) to pay. There is a recess in the film. The film is relatively thick, the touch-screen properties are not impaired. I have the impression that the film is faster than the greasy glass. But it is easy to clean. Contents of the pack are three pieces! The price is so very fair.
