1. the threaded protective cover fits well and also hampers the UMD compartment bit. When the lid is completely unfolded, however, you may not have to thick finger, otherwise you will probably never to the R / L buttons :-)
2. The protective case is durable and you can see the PSP sometimes throw in a bag, without the need to worry that they will be crushed. The PSP Slim fit with the protective cover exactly in the pocket, but then nothing more fits into the three compartments. The headphones I eg not yet accommodated.
3. The UMD bag is also fixed as the PSP Bag. There are 5 UMD compartments into which fit securely but each 2 UMDs pure.
4. UMD Cleaner: not tested and do not know if I trust the :-)
5. The adhesive film for the screen. This is a story of its own. The film sticks unfortunately on the facing away from the PSP side as well as on the actual adhesive side. The bubbles are first well sweep away, but when you subtract the upper protective film, you also film all the bubble moves back half of the screen and therefore are back. And on the film itself can not cross out one, because otherwise they scratched directly. Then've tried, then fluff are sticking remained on the film with a soft cloth. That's just stick not so difficult and the bubbles would not even bother playing a lot, because the image quality is very good, despite the film. But the dust stuck to the sticky film surface, annoys me animal.
