The derailleur is well made and does what it should. But there are a few disappointing missing features. 1> No mounting holes; The box is small and nice and small, but that just means you have to hold it to connect or disconnect USB devices. It requires either a pair of screw mounting holes or some sort of clamp that can be attached to a table or wall for the switch to snap into place. 2> No USB emulation for mouse and keyboard; Seriously, we solved this problem with KVMs in the 90's, why the heck isn't this simple feature standard.
