I think most have two brushes because of alignment, one for cd laser, and one for the dvd laser. Personally I'd save the money and get a name brand that has two brushes. But I can't really tell if it worked or not. It did run well in the PC where the other one no longer does. After applying the cleaning fluid the red dye in the brush started running. The single brush is glued on and appears like it might fall off at any moment. First thing I noticed is that it has only one brush, compared to my old cleaner which has two. My old cleaner was around 10 years old and wouldn't work in my pc but did work in the blue-ray player. I got this one because of the price and reviews. I wouldn't run a cleaner much more than that, for fear it would scratch or cloud the lens. Once a year cleaning with the Trisonic might have prevented the problem altogether. Still, a six dollar fix that brought an expensive deck from zero back to 90% is pretty impressive, especially considering that my local repair guy charges a minimum of $70 to work on pro equipment, whether he succeeds or f ails. There are still some CDs it won't play at all, that will play in the opposite deck, including one I just burned. The deck is still a little finicky, but will now play most CDs on the first try. After that, I was able to run the cleaner a few times.

It may have helped that the CD was at least spinning the brush for a few seconds. Since it wasn't playing, it took several tries to get the cleaner instructions to play. They're pretty hard to take apart to clean the laser lens, so I decided to give this a try.
