It seems I can never have enough USB ports, what with three scanners, four external hard drives, my iPod, a webcam and probably one or two other things I can't recall. I already have one USB hub - an older Belkin model - but I needed another. I bought my Dynex hub for way too much at Best Buy - like almost three times the price here. Even so, I'm happy with it. It does what it's supposed to do and lets me plug more stuff into my computer. It has a place to plug in a power converter, but doesn't ship with one. So far, I've had no reason to add power to it. It's also the smallest USB hub I've seen and it makes me wonder why the others have to be so big. Its diminutive size makes it perfect for laptops and netbooks.
