So I can not agree with regard to the "simplicity" of installation previous speakers. I've been sitting on it one hour BUT (and that's why I give it 5 stars) the end result is absolutely perfect, the film really has no tolerance margin and forgives definitely nothing that a good thing is because that I can not even watch it. I have had many films but here is definitely the best.
Tip: You can take a damp cleaning cloth and the adhesive side of lint free with no adhesive layer to affect the regulated entities.
