I used this at work -- it's what the IT guys gave me when I asked for a USB hub. It worked flawlessly for about 6 months or so. Then my computer started complaining that it couldn't recognize what it was any more, even with no USB devices plugged into it. If I powered it down for maybe a half an hour then re-connected it, everything was fine for several weeks... then it would happen again. I went through several cycles of this, but eventually it stopped working for good.
I went to our IT guys and told them it had died. They gave me another one (same model) and the same thing happened -- okay for about half a year, then erratic, then dead. Both were rev 3's.
I love the design, especially the top-loading ports. But given my track record with this hub, I can't recommend it. It would probably be okay, though, if you don't plan to keep it powered 24/7.
