【What it can do】The lens in a DVD / CD player eventually gets dusty; this especially is true if you move CDs between your indoor and car stereos. Dust reduces the optical signal and usually causes even clean discs to skip; The Reshow lens cleaner disc solves the problem. It is a nice addition to any physical media set up, especially when your hardware starts to get on the old side. | 【Easy to use】There are no cumbersome operation steps. Place the disc in your DVD / CD player and start it. A short message ("Cleaning takes 5 minutes") is followed by a left / right sound check and a musical selection (that demos your system's bass response). It will work to clean your device and even plays nice music while it runs. The most important plus is that those cds we have been playing sound much, much richer. Cleaning is complete at the musical selection's end. | 【Advanced technology】 Using advanced mirror Microfiber brushes, it can efficiently remove dirt and extend the life of the player. This will do the trick without scratching the optics. Audio CD playback starts at the center; spinning at 500 rpm and slows to 200 RPM at the outer edge. So in just a minute each of the brushes will pass the lens ~260 times, or ~600 little brushes. That's all it took. | 【Reusable】The disc can be used 30 times (brush fatigue) and the instruction sheet includes a 30 cleaning check-off. Cleaning it every few days to keep your equipment in its original state for a long time. | 【What you will receive】Reshow CD Cleaning Disc*1, Microfiber Cleaning Cloth *1, User Manual *1, 12-month warranty. And we are 24 hours standby to serve you.
