No impairment of display visibility and touchscreen functionality. You will hardly notice any difference compared to an Amazfit Verge 2 without a screen protector. Scratch-resistant due to the specially hard-coated surface! Highly resistant to scratches and abrasion! 4H pencil hardness. Intentionally smaller than the Amazfit Verge 2 glass, as it is curved, bubble-free, and can be removed at any time without leaving residue (no adhesive). Extremely easy to install! 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 leaving residue! Made in Germany - construction, cutting, and finishing at fair wages in Germany.
