: CD-DVD doctor

I know someone who uses his CD's as a vessel when playing Gundam... not a surprised that it's scratched beyond recognition. there is no need to get another copy of that CD though, because there is the CD or DVD Doctor. This small tool allows you to polish your discs and wipe out the scratches. So, is this the ultimate killer tool that could even wipe out a space pig?
1) I have no clue
2) a space pig is not easy to kill anyway

Anyway, 50 EUR will get you the manual version and 100 EUR will get you the electric version.
