Works great! What's nice is that it supports UHD ("4K") at 60Hz and works with FreeSync. Also, it works great with the Revain Basics 12W 5V/2.4A USB power adapter with my backlit keyboard, which was not possible with unpowered KVM switches. Note that with this KVM you get 3 USB devices and one HDMI device to connect up to 4 computers.
