Good modern mouse/keyboard switches are hard to find - they tend to lag, with PS/2 rather than USB, VGA connectors, etc. This thing was great while it lasted - it has one Keyboard and a mouse, a USB cable to each of the 4 systems. Better than my previous version where KB and mouse were separated. When switched on, it automatically switches to each system. But unfortunately I decided to turn it off just as I was building a new system. For hours I thought the USB ports on the new motherboard were junk, but I finally found out that it was this thing in its random buggy agony when my old system started acting weird. Great time eKL. Glad I figured that out before ordering a third Threadripper motherboard for this build.
