This is the AG+ anti-glare screen protector for Amazon Kindle Fire HD (8.9-inch). The AG+ anti-glare coating uses specially designed matte patterning. The end result is a considerably greater amount of light-scattering and reflection blurring, which makes focusing on your screen considerably easier. AG+ achieves this while actually providing superior clarity to matte films that aren't even as effective as AG+. This breaks the equation of anti-glare films, because you don't have to trade better glare-reduction for more clarity or vice versa: AG+ provides the best of both. The clarity advantage is even more emphasized on high resolution screens, like the Kindle Fire HD's display.The protector uses silicone glue for a secure, residue free attachment, and it can be easily removed and reapplied if necessary. You can use the in-depth video tutorial to walk you through installation and trouble-shooting. the screen protector is very slim, so it is fully compatible with the capacitive touch-screen and many cases and accessories for the Fire HD.
