It shouldn't be, it's not rocket science. You clean the tablet, dry it, remove dust from the surface and then apply the protective film to the stencil. Actually pretty smooth. Watching it stick to a surface is pretty cool. The first 2 times I tried this I had blisters that I couldn't get rid of even though I did exactly what the tutorial video said. I contacted the supplier and after exchanging several emails they agreed to send me another box free of charge. Accusation. I have to say that they assume your application was faulty and it is impossible to assume that the product might be faulty. OK, whatever. I received a replacement box and after applying the first one I was thrilled to only see two vials. I raised the glass over the bubbles and then dropped it back into place as instructed. The good news was that the original bubbles were gone. The bad news is there was another bubble in the corner of my tablet that I couldn't remove. I finally succeeded on the fourth attempt. He made a bubble, lifted the glass and put it back in place. Bingo. You know, it looks like a good product. But when I need one again, I find something else. I've never had so many problems with an app.
