The color is not extra and finishes the edges either, okay, but at 7 euros I think it's a great product. It is easy to put on and, like any self-respecting protection, difficult to remove. In any case it makes its protection work. As for buttons, they work and personally the fact that they are a little harder to press is largely offset by the fact that the feels better in the dark and the buttons original risk nothing (a friend lost his volume knob on a Cowon S9). So my advice but I can understand that the white rubber appearance may put off some.
