As a result of using this protector on my MP3 player i found that the crystal-clear display was preserved perfectly, with no reduction in screen sensitivity .The tempered glass provided an extra layer of protection against scratches and cracking. This product is affordable, easy to install, and it has not affected the look of my electronics. The only drawback was that it did add a bit of thickness to the player, but that's a small price to pay for peace of mind. Highly recommended for anyone looSee full review
