At the touch level, sensations are the same and just touch the screen to be able to do what one wants. By cons, what bothers me a bit is all the little bubbles that I have not managed to get rid two months after the first pose; I must say that the tiny card that is provided is for much: how do you ask the protection and expel the air with such a small object? To give you an idea, the card measures 4 x 3cm. For a screen of 11.6 "Besides the banks, it's lightweight.
Highly recommended if you master the pose of the transparent film; That said, even if there are bubbles, the protection performs its functions.
