Review on 2 Port USB HDMI KVM Switch with Dual HDMI 2.0, USB 3.0, Triple Monitor Support, Audio, Integrated USB Hub, HDCP 2.2, HDR10, EDID Compatibility by Cody Hunt

First all the pluses: Works great - supports USB 3.0, all the necessary cables are included, a wired remote control so you can hide all the connections behind the monitor, the possibility of the sound signal turning on and off when changing inputs can only be powered from the USB 3.0 port it is plugged into. You can also use hotkey combinations to toggle the input. It basically worked fine from the start - I connected 3 machines to it - a desktop and two laptops. Will drive a 4k monitor at 60Hz via HDMI. The ONLY negative is that the instructions are a bit confusing. For example it comes with a USB power cable which I assume is for when you connect USB powered hard drives to the unit and need more power but this is not mentioned at all in the manual. The manual says you can manage two or four computers, but I use 3 with no problems (not sure why they didn't say "up to 4"). It's really finicky because it works great.
