These screen protectors are the best i have used. They come between two peelable outer layers, so you peel one layer off, stick it down, then peel the top layer off. The only trouble i did have was that the tabs you use to pull the top layer off with actually pulled the whole protector up instead of just the top layer, so in the end i just ended up using my fingernail to peel it off.
Once the application is completed, however, the feel of the protector is as smooth as the iphone sceen, so it really doesnt feel any different. It is much easier to get smudges on it than the iphne screen, but then again they are easy to wipe off anyway.
A 5-star product from an excellent seller.
