which one are you looking at specifically? there's a couple different manufacturers i think.

#000 philip's screwdriver:

this is the one i got, made by XCM. i think it's the cheapest of all of them.
as far as quality goes, you definitely notice that it's not made by sony...
"1) Is it good to change the faceplate ?
2) Which wan is better? faceplate or stickers?
3) Is it easy to change ?
4) Im worry if i change some of my button will not work . how to ensure ?
5) What if i drop my psp and the faceplate crack . as u know its non original type of fp"
1) yes. voids warranty, but i don't think any of us have qualms about that.
2) faceplate, imo, definitely
3) yes, it's easy. you'll want a #000 philip's head screwdriver. you can use a #0 or a #00, but you run the risk of stripping the screws with too much pressure (or too little pressure... it's really worth the money to get yourself a #000 philips). there are plenty of tutorials with lots of pictures. just make sure you take your time, and it isn't difficult at all.
4) if you have any problems after you've done it, if you describe the problem to me, i can most likely identify what you did, and how to go back in there and fix it. but i bet you won't have any problems.
5) don't drop it...? i mean, if you drop it and your faceplate cracks, i would go ahead and put the original back on, or order a new one.

i don't regret putting the green faceplate on, but it's looser than if i had just left it with the sony faceplate, and i have gotten bits of dust in there over time. i just opened it back up to clean it off though.
i want to get the full body clear replacement. that is on my list of things to purchase.
