The Hydrogel Protector most significant advantage is that it heals itself as the name suggests from any minor scratches ensuring the life of the protector and giving you an unobstructed view of your screen. Also, it is very transparent that keep the display active and visible on the device. The hydrogel is thin and flexible — enabling improved touch sensitivity and addressing the need for a curved screen-edge fit (the same quality that would enable a better fit to some phones with curved screens). The protector is simple to apply and remove, with no residue remaining on the adhesive.
