Yes, somehow a tiny air bubble is always there, but mostly at the edge and so barely visible. The films are made to last and are really easy to stick, even though I'm not a Fimmelmaster. Just the screen with a suitable cloth and then also really gone all dust crumbs which you can still see what I had never (of course you can find safe nano-crumbs with a magnifying glass ...), then slowly and drauflegen straight and see there, glued as it should.
Does what it says, protects my display, and the price is also ok. So 5 stars.
