TESmart 4 Port HDMI KVM Switch 4K Ultra HD 3840x2160@30Hz | 4x1 KVM Switcher 4 PC 1 Monitor with 2x1.5m KVM Cables Supports USB 2.0 Devices Controls up to 4 Computers/Servers/DVR-Matte Black

I purchased the 4-Port version of the KVM as I work from home and use two company and two private systems when doing so. This KVM looked like the perfect way to easily move between using all of my systems with having multiple peripherals on the desk. You only get two sets of cables with the 4-port version, so bear this in mind if you don't have spare USB A-B or HDMI cables lying about. Really easy to set up and using HDMI, I now have my speaks plugged into the headphone out on my monitor. HDMI carries both video and audio, so the speakers play audio from whichever KVM port is in use. This unit has made my life a lot easier and productive, so I could not be happier.

Works well. Had to contact support to fix an issue, but they were responsive and it turned out not to be a problem with the KVM. Feels reasonably well made and the keyboard switching works fine.
