A perfectly processed, very well designed hub. I use it with my laptop. Super things like hard drive, keyboard, mouse, printer, or anything that can connect to the black stationary part what you want is not always free connection and disconnection. The power supply is working properly and provides enough energy, not like in these low-cost hubs, where the power cord only alibi is moderate here. Whatever the mobile part is ideal for USB sticks or the like and if you with his laptop goes on "Travel", you can simply take it and you have here a small mobile hub. As for quality, I can not complain really, for my part. The build quality is great and so far I do not mind even noticed negative. The device is really worth its price.
