The price is right for such a little item that does such a big job. I consider them essential. When offered by Amazon(I see they are only available from outside sellers at this time), they're a great buy as you can throw them in your cart whenever you need just that little extra to put you into the free shipping range.

And... Don't forget about the CD and DVD players themselves...cleaning the lenses occassionally also helps to improve perfomance. I use and recommend the Memorex CD/DVD Laser Lens Cleaner. It does a good job, is reusable,performs optimazation tests(that checks your system), and is a very reasonable price as well.

And don't forget... always clean your CDs in an outward motion starting from the center(never circular).

Go For It....Laurie
