In both films, as many bubbles have formed, that was incredible. I'm using for years protectors for my mobile phones and iPads, but this was by far the worst quality I've experienced.
I thought after the first try, okay, maybe not cleaned properly. Extra Habs again cleaned with a microfiber cloth and the 2nd film tried - with the same result.
So money spent in vain, the films were disposed of immediately.
The article I can therefore only recommended if you do not mind to have some bubbles under the film.
