Great KVM switch, I connect my work laptop, personal PC and Nintendo Switch to it and they all switch pretty smoothly (takes about 5 seconds). Works with my 60Hz 4k monitor, wireless mouse and wireless keyboard. It also has an extra power cord, but it seems to work great without having to use it. Comes with 4 USB cables and a small optional wired remote control. 3 common ports as described, for 4 devices as described. Best deal I could find for $40.
