[EX Q]: This is an excellent product. Much better than the hard plastic ones found at most stores. I am very happy with it and highly recommend it.
[EX A]: Good Review

[EX Q]: 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.
[EX A]: Good Review

[EX Q]: Don't waste your money. This will not work for more than 10 minutes even if you have brand new batteries. Then it stops. Just like that. Do yourself a favor. Look elsewhere. The cost is worth saving some time. It doesn't seem to be possible that Amazon can sell this junk. So what kind of rating system? Would I put four or more? Zero stars seems much too high.
[EX A]:
Bad review
