Summary: Very small and compact. It has four ports on front and three on the back, this makes it useful for connecting MP3 players and cameras for the front ports and hard drives and printers on the back. A couple cons. This unit gets really warm. I think this is because it is so small and it has it's own power supply. I had to raise it on a shallow plate so it wouldn't be warming up the top of the pc. Another issue is that it gets cables sticking from all sides.
Summary: After 5 months of use, the thing seems to have died on my. It gets so very hot, I'm not surprised. The ports became flaky. Everything that didn't work any more on the hub, works perfectly on my computer's built-in usb ports. I gave it two stars because when it did work, it worked fine. But I need reliable things.
