No impairment of display representation and touchscreen functionality. You will hardly notice any difference compared to a Pearl Newgen medicals SW-260.hr without a display protector. Scratch-resistant due to the special hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the Pearl Newgen medicals SW-260.hr glass, as it is curved, bubble-free, and can be removed at any time without residue (without adhesive). Easy installation! No bubble formation possible on a dust-free display! When applying the film, the air is displaced and it adheres to the display as if by itself. Can be removed at any time without residue! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
