I needed this for my WFH setup and it suited my needs perfectly. There are 4 buttons on the front as I didn't want to switch between all 4 ports to get to the right one. But it also intercepts keystrokes, so double-clicking on CTL + port number (1-4) and <enter> also toggles. The only minor flaw was the audio, but that's not the fault of this device; this is how almost all HDMI KVMs work. My solution was to plug the USB audio dongle into the USB port on the front of the unit - it toggles along with the K, V and the mouse. I also appreciate the reset button on the front, but I've only used it for troubleshooting, the unit hasn't hung up during use yet.
