Title: Overpriced junk
Review: All this is is some cheap plastic with some cheap fans, the USB hub really doesn't justify charging 50 bucks. I've had one of these for a couple years now (bought it while it was on sale at a store). If it works, it does its job, but that's a big if. Sometimes the fans start grinding for no apparent reason for a few minutes, then work perfectly. Sometimes they start grinding, then continue grinding. Powering it on USB (rather than the AC adapter) sometimes resolves the problem (as it runs at lower speed). Lately, one of the fans has been grinding almost continuously, I suspect the motor might be shot.
