The foil is designed correctly for the handset. has good matt, non reflective texture. this makes it good to read in bright light conditions even with less Display Brightness. so works well for battery saving too. The foil does not impedes the touch sensitivity of the screen in any noticeable way so That is a plus too. the instruction to apply it on your phone are Relatively simple, quiet i advice you to watch a video on youtube just so u do it right in the first attempt itself. I recommend strongly to buy this product.
