Memorex has an excellent product in the Optifix Pro disc cleaning system. First, it is simple to use, my twelve year old son uses it. Also, it has saved quite a few of my expensive CD's, DVD's, and data discs. To be honest, I have not used any other products of this type, but this one certainly lives up to the manufactures claim that it will fix most damaged discs! I highly recommend this product if you own any substantial quantity of DVD's or CD's, and wish to extend their usefulness. Great product!
