I have purchased this drive to use with my Netbook.
I use it whenever I need a new CD for my car or when I need to download music from new CD's. I have also used it watched a few DVDs as carrying this and my Netbook combined still take up nowhere near as much room as my old laptop. It is powered and connected by USB, and the drive has a low profile and makes a minimal amount of noise. There are a few LED's which indicate that it has sufficient power, it should run off one USB but a red light means that you need to use the second USB cable for additional power.
Admittedly at one point I was confused, as once there is a DVD in the drive I was unable eject it, and I had to do eject the disc by ejecting it by clicking "eject" on my computer> I did have to read up on this before I realised this, as for some reason the button on the DVD drive itself is non-responsive with a DVD in it!? This has in no way been a problem for me, just a minor inconvenience, that was overcome in minutes.
It works just as I expected it to, it is excellent value for money and it looks better than I anticipated. Overall, I am very satisfied with the price, quality, functionality, and convenience of this product, and I highly recommend it.
