I bought one a month ago for my mini notebook, because it only has two ports so I needed to expand it. One problem with laptop USB ports is that the are too close to each other and too low down. This is a problem when you try to plug a cable out as well as in. The swivel system makes it very easy to plug in a USB in and out without having to move the laptop around. It comes with a power supply that can boost the power if needed. Apart from the obvious features, it seems to work with all devices. I have a dozen hubs of all sorts, but when I plug in, lets say a portable hard drive, most of them do not get recognized by Vista, but when I plug the same device into this, it work without a glitch. I am very pleased with this and am buying another one. I have had a lot of problems with hubs, so trust me when I say this is the best I know.
