These films prevent reliable, as far as I can ascertain after about 2 weeks.
They are supplied in 6-pack (3 each front and rear); they are very thin but hard - flexibility in something like a solid sheet protector. It is important that correct positioning when attaching and absolute fussiest dustlessness. Otherwise, you can see every speck of dust and embedded any fluff like under a magnifying glass. Do not ask how I know.
The film material is so good that I can find to use and feel of the touch screen no difference before and after installation.
