All prior repair kits I've used just made the CD much worse (such as the Memorex OptiFix, which RUINS CDs instead of fixing them) or marginally better (Disk Doctor). The Disk Doctor at least repaired the CD correctly but made it look butchered; good luck selling one, it would look like you took sandpaper to it.

This one, however, both removes all reasonable scratches (if it's too deep, sorry, there's nothing in existence that will remove it) AND makes the CD look brand new. It is a long process, not a 20 second "stick it in and forget about it" procedure, but the end results are incredible. You have to work for it, maybe half an hour on a horribly scratchy disk, but this thing will work miracles!!!

The instructions are vague and hard to understand because this machine is from China. After using the machine for a few months, I got the hang of it and use it a little differently than the instructions suggest. I get fantastic results by using the white pads 90% of the time. The yellow pads are only used if the discs is completely thrashed. The liquid polish is the best stuff to use. I also use the creams with the white pads if the disc is very scratchy. I sell DVD/CD's for a living and this machine has greatly improved my sales and prices. A must have for all sellers of DVD/CD/Games. It will pay for itself!

All I can say is, I'll never have to worry again if I get a DVD and it freezes or skips! I recently bought my wife a 25 DVD set, and halfway through the first disc it froze. I started looking up repair machines and almost went with a another one due to the price of this machine, but after reading the Amazon reviews I picked this one. After receiving the machine, I followed the instructions (with a slight amount of difficulty, as they were a tad confusing), and about 5 minutes later it was as good as new!! It seems I'll never have to return defective DVD's again!! Well worth the cost!!
