I've had cheaper USB hubs, but this one is much better than any so far. Firstly, its powered (it needs a power socket), but this means it can deal with power-hungry devices like external USB hard drives, without overloading. You don't have to have the power on for low-power devices like memory sticks.
Secondly its robust - it doesn't fall of the desk all the timen and its got little rubber feet so it doesn't slip about. Its got a full set of indicator lights. OK, its nothing to get that excited about but it does the job with no problems. I'd buy it again, and that's recommendation enough I think.
