Waste of money. The size of the screen protector is *exactly* the same size of as screen (and I mean to the nearest micron), which means it's practically impossible to align it first time without one side over the edge, leaving annoying air bubbles. (Now you might think you have a steady hand, but so did I, being an amateur painter.) If you try to take it off to re-align (as it says you can) the static immediately pulls all sorts of dust onto the underneath, rendering it useless. Mine is now in the bin.
I'm giving this two stars because, having read this review, you could buy it and trim a hair's width off the side of the protector to avoid the problem.
