This may be great for a TV DVD player or stereo CD, but it doesn't work in my iMac computer. (2009 27" Intel Dual Core) It loads into the optical drive and then just sits there. The computer doesn't recognize it as a CD or DVD, doesn't open iTunes or DVD player, doesn't spin, doesn't play, doesn't do anything. Amazon was great with the refund, so no big deal, but I don't think it's made as a computer Optical/CD drive cleaner. At least not for mine.
