I purchased an Insignia Laser Lens Cleaner so that I could clean my CD player and the CD/DVD drives in my computers, and I believe this laser lens cleaner did a pretty decent job. I've never bought a CD/DVD laser lens cleaner before, so I didn't really know what to expect. However, I was surprised at how easy and intuitive it is to use. The laser lens cleaner plays in multiple different languages and cleans your CD/DVD drive very, very quickly (it surprised me at how fast it was). You need to put it into the CD/DVD drive that you would like to clean and play it on track 2 after you start (track 1 isn't in English). It will tell you to wait for the beep noise that comes later in the track, and when you hear the beep noise, you need to switch to track 9. Track 9 tells you that the laser lens cleaner has finished, and if you want, you may listen to some music that is already on the CD. That's all there is to it. I wish there was a better way for you to notice if the laser lens cleaner actually did clean the CD/DVD drive and how well it did clean it, as it only appears to have improved performance marginally, to be honest, but I believe it did a pretty solid cleaning job. Overall, I don't regret my purchase, and I would recommend this to anybody who needs to clean their CD/DVD drives (whether in a computer or an actual CD player).
