I rarely write reviews but wanted to share my experience with this product. We had a Pioneer surround sound system for about 6 or 7 years which we used almost every day. He's been getting loud and has recently stopped reading some discs and has trouble reading others. It was getting worse and worse so I just thought it was about time so I started shopping to replace it but forgot how expensive they are which made me change this thinking given the cost we had to lose to try. Very easy to use and did the job. For about $7 and 4 minutes of work, we're back in business. These aren't instructions that I could find, but I just pasted them in and they started on their own. It's very quiet, so it doesn't seem like it's going to do anything, but it is, so I just left it alone. He cleaned for a few minutes, then tested each of the speakers and let me know when it was done. Be a little careful though as there are 3 tiny protrusions on the bottom of the disc (shiny side) which are brushes so I will be careful not to touch or damage them when removing the disc.
