The GameSir VX AimBox is a device that facilitates the use of a mouse and keyboard on consoles. Xbox introduced mouse and keyboard support a year or so ago and it was a hit with players. Since then, questions have been asked about this level of support to no avail (as far as I am aware). So, there is a market for this type of product. So, lets have a look and see if its any good.
