I was having problems reading discs in some of our DVD players and especially our computer drives. One of the drives was so dirty that it was not even being recognized when a disc was inserted.When I received this Lens Cleaner Disc I tried it on the worst drive that was not working. Wow! It really worked on this drive so that it is now recognized and works great. Just insert the disc and as it turns it is starting the cleaning process. There is audio in several languages that give use instructions. After using it several times I now just go to track 6 and start the cleaning process.This cleaner has done wonders on so many drives that we feel we have more than received our money's worth. We will definitely replace this whenever it wears out. I do not know how long it will last as we have been using it for about three months so far. We have cleaned the drive in the TV that was skipping and now it works like new. All of the DVD players and video game consoles have been cleaned as well. I actually have a stack of old CD/DVD drives that stopped working and when I get a chance to check them out I believe that some of them may just need to be cleaned as they act the same way the drive on my computer did before it was cleaned.This is the only product that I have ever rated 5 stars across the board. The product works as advertised. It will not fix a defective lens but if it is just dusty/dirty then it will clean it. The price is reasonable for the service that it provides. The shipping was very quick and overall a great product.This is definitely a product that I would recommend that everyone should buy. Almost everyone has a computer or CD/DVD player that could stand to be cleaned. This would actually make a nice gift for anyone who does use their computers a lot as either a corrective or maintenance measure.
