Too big to fit on PSP slim
This product is NOT designed for the PSP slim and it will NOT fit the screen. The product is too big (about 3mm in height and 1mm in length). I tried cutting it with a razor blade, but then it doesnt stick to the screen around the edges that were cut.
My advise to you.... DON'T BUY IT.

GOOD PRODUCT 5/5 BEST PROTECTOR
For those who complain about the Offical PSP screen protector are NEWBIES and weaklings. Most of the people just take out and stick it right away . But its wrong theres a special cloth inside to make all the things gone by wiping it and then you stick the protector. I bought this 2 years ago and its still fine. Do not buy other psp protectors that are not Offical sony products , they may and might made your screen with reflection marks that cannot be clean away and sticky marks . As tested this sony product is the best in the market . Only newbies do not follow the instructions and put it right away. Follow the instructions !

not good
The clarity of the screen protector is great, which is why I gave this 3. However.. It is cut much too big for the PSP screen. This leaves edges on the top and/or bottom not sticking properly due to the surface not being as adhesive as the screen itself. This allows dust and dirt to enter from both ends over time. Try the Hori line of screen protectors, they are the superior product.

Excellent Screen Protector
Might Want to pick up two of them if its your first time putting one on.I bought mine 7-8 months ago and its still working great. I even bought a couple extra because I liked them so much. Great product!

good but...
The screen protector is quite clear but first of all, the screen protector is not cut to size. It is a little bit bigger than the screen itself.
