Well I purchased this for $15 from fry's and tested it on some drives I had for Xbox360's lying around and some PS3's only problem you need for the disc to be read in order to use the disc cleaner, I have other brush cleaners that are CD's which are read by anything so since its a DVD its not really that great as for "wind tunnel technology" the acsents in the voices of the DVD are pretty funny "Disc Creaner" and they have the death video from "soilent green" plus some really bad 3D models of a living room so not only does it clean its comedic.
