I got this stuff because i really wanted to remove scratches from my cell phone. To get to the point of whether it works or not, it does. Although you do have to work at it. At first it looked like it was making the scratches worse but i kept at it because i was not gonna just leave it looking worse. I had to apply it several times before the scratches were polished away. So the scratches are gone now but the down side to that is that now my screen is all rippled looking. Maybe i did it too much but also it isn't too noticeable when the phone is on and in use. When it is off or the screen is black it's kinda noticeable but if you were to run your finger over it you can for sure feel that it's not smooth. The product itself is a white paste and if you were to rub it between your fingers you can tell it has a very fine grittiness to it, so it pretty much sands and buffs away scratches rather than fills them in. so if you are looking for a product to get rid of scratches but you want something to fill in the scratches this isn't the thing for you. Also it might make a difference on what your screen is made of. My screen isn't glass so i don't know if that makes a difference.
