Question: I use these to replace the filters on our air quality monitor. They have done a good job and are just what we needed at half the price that is typically charged. Thanks. :-)

Answer: Good Review


Question: I bought this to use for my new iMac 15", which has a DVD drive (usb) but no card slot. When the product arrived, it was smaller than expected, about half of its size. However, after trying it in two drives from different manufacturers and several DVD-RW discs, I'm satisfied enough with it. It's not fast, nor is it quiet; It operates much more quietly (and less noisily) then my USB optical drive. If you just want something that's portable and cheap, try this.
