Nintendo DS Lite Protector (Clear)

Clipped in very easily and feels very secure, though I think taking it off would be harder than advertised. Because it's the US version, instructions with the box are in English.

Does appear to scratch easily though, but it's better that the protector does and not the DS, right? It has a rainbow sheen in some light (like in the light of my monitor) and some rainbow oil like blemishes on the top. Rating 4 and a half stars.
