Despite numerous attempts, I can not ask this product without air bubbles (or micro dust) under the protective film. The pause, if possible on a small screen (eg iPhone), seems impossible on a screen the size of an iPad Air. So I think this is useless on the iPad. It is useless to have a retina display if it is for him stick a plastic film which significantly degrades the visual ...
I want to clarify that the problem is not the supplier (I had the same problem with the film comes with protective cover I bought), but the product itself.
