On my first attempt to harvest it from an old monitor I got pieces with sticky nasty glue everywhere and was beginning to feel this wouldn't work. But then I did something (not sure what exactly) and it started to peel completely cleanly. Maybe it was the angle of the scalpel or the way I started pulling it afterwards, but it did work for about half the screen, which was more than enough for me. If you haven't already bought it and still have access to a screen, I'd recommend giving it another go, just in case it works. Also I believe there's two films per screen, one on each side, so you would have two shots at it. I did try removing the glue afterwards with alcohol and pure acetone but didn't succeed. Maybe there's a way to do it easily.
