This product works, mostly. If you have pretty deep scratches on your electronic device (in my case a PSP), you'll need to do some extra hard scrubbing with this stuff. I was able to mostly get rid of the scratches, but it took some work. Make sure that you realize that this stuff aint magic, that it's going to require some work from you. When it buffs out the deep scratch it leaves what looks sort of like a smudge, but that's only visible in a certain light at a certain angle, this in turn buffs out the scratch. A good product.
