The film Crystal Clear is most suitable for the Acer A500. The surface is smooth and not as rough as in the film ANTIREFLECTIVE which is not suitable for the Acer. Also with regard to the use I've come to the result that this film best ist.Sie not only protects against scratches and attachment is easy, if you need some time mitbringt.Über the fit you can not complain. There are worse film where one has seen vornerein the that does not fit.
