Invisible and eternally durable.

Had to replace my old, because my daughter has taken off and she could no longer free of dust onto the display. The first of 2012, all unscathed: mud, greasy fingers, multiple drops, wet and dry sand, etc. Real indestructible and invisible to the end. No contact problems even with touch gloves or very dry fFingerspitzen. Is it possible to attach well, fits perfectly.
