I cleaned the screen as recommended in the directions, put on the screen cover, and got quite a few bubbles that I couldn't get rid of. I would have been able to deal with the bubbles, but I couldn't deal with the sticker residue left from the 'helpful' little white tab that was put on the cover to aid in removing the backing. Actually, I did put up with it for about 10 minutes, then I tried to type up a text message and my keyboard lagged a whooole lot. Very annoying. The protector is currently in my trash can. Oh well.
