I bought this for my XBOX 360 and it worked fine; just popped it in and the verbal instructions played straight away (the console recognised it as an audio CD). It seems to work fine on everything I have that plays DVDs or CDs, but doesn't work on the Wii.
The Intro is on track 1, English instructions are on track 2 and then it tells you to forward to track 9, the whole process takes only a few seconds; although there is some very dodgy music for you to `enjoy'. It comes with a large bottle of lens cleaning fluid, considering you only put one drop on the pad each time you use it. Attached to the underside of the CD is one little pad and one little brush. It seemed obvious that you only put the lens cleaning fluid on the pad, although there were no instructions to that effect.
It's a good price and the thing works; I considered dropping it a star for the dodgy music, but then thought I didn't buy a CD lens cleaner to listen to the music!'
