Query: don't waste your money

While this unit is slightly better than the $39.00 cd polishers, it lacks power and heats the cd's causing the foil data layer to peal and it just doesn't cut well enough to remove anything other than mild scratches and scuffs. There are other units on the market that cost quite a bit more but for the price I'd expect better. The cutting pads for instance cut unevenly. It needs to be water cooled and use better compound. I'm going to try some compound from an Auto Paint store. Basically this machine is just not worth it.
