I did everything according to the instructions (steam, remove dust with a napkin and wipe off, stick on, etc.) and still had blisters. It also generates a lot of static, so if you need to tweak it, going back to natural forces will be difficult. You spend your money on this product with all the packaging, like a 1 sheet glass school yearbook. There should be at least 2 panes of glass in case you mess it up or it breaks and reduce wasteful packaging.
