UD-3900 Plugable USB 3.0 Docking Station for laptop extra USB extender We got this so we can run more than one monitor. We then managed to get a very wide monitor which now means we don’t need this. We took it out of the packaging and had it to one side but never actually set it up. It does not have a UK plug so you will need an adaptor for US to UK plug. Many thanks
