I purchased this external DVD drive specifically to use with my netbook (which by definition has no DVD drive, on holiday. It has proved a useful gadget, enabling me to use my (rather ancient) Microsoft Autoroute software to plan routes while we were away.
As I have a chronic illness, I have also found it to be useful for listening to CDs and watching DVDs on the netbook when I am too unwell to get up. It was necessary to download software from the Internet in order to watch DVDs, but VLC Media Player is available as Freeware, and downloaded to the Windows 7 netbook with no problems, so that was easily sorted.
I would say this is very good value for the money, and I would recommend it to anyone else in a similar situation to myself. I noticed that some reviews said it was noisy, but I have not found this to be a problem.
