Clinton,

I think I paid about $5.00 Canadian for this stuff. I have probably successfully repaired 5 CD's of my own and two for a buddie. I also had 2 that it didn't completely repair. It takes about 2 minutes per CD. So for under 20 minutes time investment and $5.00 I have saved seven CD's, I figure at an average of $15.00 each I'm up about $100 versus replacing them.

The FAQ section of their website does say that if they are scratched on the top they can't be repaired.
