This is a very handy little device that is both slim and extremely lightweight. When it sits on the desk it isn't very noticeable and makes it very easy to quickly switch the cords between my desktop and my laptop. I'm a Mac user and this device works just fine with my computers. I didn't notice any appreciable slow-down in communication while running devices through this USB hub either, which was great.

My only complaints:

There are two cords for this very small device, one for power and one to connect to the computer, and they are different colors. I'm sure they had a reason for making one black and one white, but I thought it looked a little tacky. If you are able to tuck it back behind something so it's not visible, this won't be an issue.

I also wished that the device didn't require it's own power source. It would be nice if it could draw power directly from the computer so I didn't have to sacrifice a separate plug for it, but that's not a deal breaker.

Conclusion:

Since the USB ports on my Macs are fairly easy to access, this isn't something that I really needed, but if I was running a PC with a tower and all the USB ports were on the back, I think this device would be invaluable. It will give you easy access to a USB port without blindly searching in the back of the tower, and it will take up very little room. It's only a little bigger than a pack of gum.
