Scratch-resistant, hard-coated surface with 3H pencil hardness. Test winner of the c't magazine 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 FitBit Versa 2 glass, as it is curved (see photos), it is bubble-free and can be removed at any time without leaving 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 impairment of usability! The dipos screen protector offers a pleasant touch experience and is optimized for the FitBit Versa 2.
