It's ok if you just want to clean surface dirt off your cd/dvd's. Simple and quick to use. However the solution included is just a cleaning solution and it will not repair scratches of any kind.
Look elsewhere if your discs are scratched and you need a disc repair system.
Edit: Have been contact with seller after they read review. They offered a partial refund if I kept the item to use as a disc cleaner which I accepted. (They also offered a full refund if I returned item but decided not worth the hassle of postage.
Didn't appreciate the inclusion of instructions of how to delete my review though.
