I own my PSP for some time now and there have also so it settled some scratches. So I thought, so a film can hardly hurt. The trouble is: Who takes care not exactly dirt and leaves on the adhesive side of the film, who gets the no longer so easy since gone. But a little tip from me: Who spotted the adhesive side, it should with a strong, warm water jet (liable later still to the PSP to) clean and a lot of patience, the film and apply to the PSP. Not dry the film, because so come back lint on the surface and with the drops, the film can be applied more easily.
4 stars because the film was difficult to apply and also slightly protrudes the protective casing on the bottom of the PSP, which does not look very pretty. Toll is that the PSP to the protective housing fits in the pocket. In addition, in the case are still small pockets, there you can conveniently stow eg its memory sticks.
