I use this USB hub on my daily workplace to have a few appliances connected to my laptop. Because I take it with me quite often, it just saves a lot of time and cable management being able to plug in four USB devices at once.
But when you turn off the ports, they still get a little power which can be annoying (depending on the thing plugged in, e.g. sound interface). Also I wished that it would remember which ports I turned off, maybe actual switches would be a better option, and the cable would be longer.
Anyway, a great little USB hub.
