Summary: nice to be able to unplug ONE usb connector from laptop and pick it up to carry to kitchen, etc. Instead of having to unplug this and that. I have an external keyboard, 2 external hard drives and one open port left over on this, and two more ports in back of lappy for fun (one taken by radio mouse thingie). still, it does a horrible job washing my car.
Pros: It works well, nice small size yet big enough to plug in the USB cables. I Like how it plugs into itself the built in short usb cord so that it is portable. The usual from Belkin - it is affordable and it works.
