over the years I have bought many different types of hub, mini-hubs, powered hubs etc etc. This one is the best i have ever used. No bigger then it needs to be, and so far it has worked perfectly.
Only minor negative comment - which is true of most accessories - can't the AC adaptor be smaller? for a 500ma adaptor it seems huge. Nokia at least have started to make smaller adaptors/chargers for their phones. Would be nice to see other manufacturers follow suit. The adaptor is as big as the hub itself!!!
Do not be worried about the comment from a reviewer that if you plug a USB1.0 device it will slow all ports to USB1.0 speed, - That is a feature of USB and all hubs.
