Query: Collecting dust

Well, technically, it works! I bought this over a year ago, and I was able to restore two or three dvds right away. But for the price, I should have just bought used dvds that work. One go only seems to strip about 80% of the way around the dvd. The replacement wheel costs too much to bother buying. I would recommend only buying this for dvds that are irreplaceable. And don't kid yourself- you can't effectively buff these dvds by hand afterward, I tried. You will have to strip more, using up more of the wheel's precious grit, and your dvd will look like crap. Either buy a buffer, or take your resurfaced dvds to a game shop to have them buffed for a small fee. I don't think I quite got my money's worth out of it, but will just cut my losses.
