I have one and it works. As RJA says, I believe that the biggest benefit is in the truing and balancing of the disc. I accidently found out, on an REM CD that has no artwork, that it works best when lathing the top and bottom. It trues the CD completely.
That said, I've found that some CD's already come balanced, in which case any improvement is very sight if any.
