Scratch-resistant, hard-coated surface with 3H pencil hardness. Test winner of the magazine c't issue No. 3 (2012) in a test of anti-glare films. Among manufacturers like Belkin, Folix, Hama, hsw3000, Moshi, and 3M, the dipos anti-reflective film is the only one rated "very good" for glare reduction. Deliberately smaller than the back glass of the Xiaomi POCO X2, as it is curved (see photos), it is bubble-free and can be removed at any time without residue (no adhesive). Easy application - 100% bubble-free installation on a cleaned display! The special silicone adhesive layer displaces air during application and naturally conforms to the display. No impact on usability! The dipos screen protector offers a pleasant touch experience and is optimized for the back of the Xiaomi POCO X2.
