The anti-reflective coating improves clarity and readability plus minimizes glare making the screen easier to read in a variety of lighting conditions. ARMR's full surface adhesive, rather than perimeter only adhesive, allows no gaps or bunching and enables the film to be removed easily leaving no residue. 3M ARMR200 is designed to last up to three months, depending on use, and then can be lifted off easily. Reapplication in the field is simple to help keep your handheld device screen in top condition.
