Does its job well, but not suited for 4K monitors.
I use it to connect a Window 10 and a Linux (OpenSuse) machine to 1 set of Monitor/Mouse/Keyboard. It works well and switching is pretty fast. However when switching to Linux the display doesn't always wake up properly. This however is a problem with Linux not the switch (X11 related). To fix it you can set a fixed resolution in xorg.conf. I have not tested it with Wayland yet.
Pro
Easy to setup and use

Only Display Port version 1.1 (this means no 4K at 60Hz)
