No impairment of display visibility and touchscreen functionality. You will hardly notice any difference compared to a Garmin Venu (43mm) without a screen protector. Scratch-resistant due to the special hard-coated surface! Very resistant to scratches and abrasion! 4H pencil hardness. Deliberately smaller than the Garmin Venu (43mm) glass, as it is curved, bubble-free, and can be removed without residue at any time (no 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. Removable at any time without residue! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
