I was a bit wary about buying these after reading the other reviews, but I think protection is essential so I bought them anyway. They work perfectly. As long as you scrupulously clean the screen before you try to apply them, then give the screen a good dry clean as well, then - starting from the button end - apply the cover little by little while keeping the backing on as much as you can until the adhesive surface meets the screen it will be fine. I used a piece of kitchen roll (lint-free) to push out air bubbles as I went, and though you will NEVER get rid of all of them on a screen as big as this, I only ended up with one tiny bubble and you can't see it anyway once the IPad is turned on for use. This is cheap as chips and just requires a little care and patience.
