I really like the Maxell laser lens cleaner.  I think it is better than some of the other brands on the market.  I believe the Maxell cleaner cleaned my DVD laser much better than another one I had purchased.  You can't see the underside of the disc until you open the package, but the Maxell disc has a little brush embedded on the underside, whereas the other brand I had purchased did not.  Perhaps, this is why the Maxell cleaner did a better job?
