It's not just you it's you and your friends. No bubbles here. If you have bubbles, yer doin it wrong.Tried them all, for iPad and iPhone...No amount of care results in anything other than bubbles...Packs of them just gathering dust....It's not just me being inept, friends have tried to do it with the same result.

Sounds like you were using the wrong screen protectors.although my last iPad 2 before I sold it had no screen protector and it was so much better to use without one.
