Purchaed this supposed DVD/CD cleaner to clean my Sony and JVC DVD Player/Recorders. Saw NO improvement on DVD's and would NOT even load on either of my Pioneer 6-Disc Mag Players. Useless product and big waste of money. I had used Memorex's OptiDisc DC/DVD cleaner previously, but wasn't completely satisfied with cleaning, so was hoping this cleaner would be better based on reviews. But it was not. Do NOT Buy.
