The Joytech Armorlite case fits perfectly on my PSP3002 model. You don't need to remove the case to insert new games or to change the memory card as it's designed to open in the back and shaped to open memory slot, all the important parts are exposed (such as the earphone socket, power socket, and buttons) for convenience. It makes the psp slightly more bulky, but hasn't effected my game-play.
