After I already wanted to use two protective films from other manufacturers for my 3DS XL, but these were not satisfactory, I opted for the protective film from Mumbi. As has been pointed out then, my choice would have to be covered directly to this product, mainly because two films are included, if the attachment on the first try is not successful. The film is tailored to the millimeter on the screen what the attachment difficult, but has in the success of optimum protection. Bringing these somewhat askance, as occurs what is described in some reviews here: The touch screen unresponsive. But this is not because of the film, but the fact that you have this installed wrong. In the case Simply peel off and reposition or settle and use the second film. The film protects the screen perfectly and the image quality is not compromised.
