I needed to add a work laptop to my dual monitor home system. This little box made it painless. It only worked by plugging everything together. It easily accepted a Logitech wireless keyboard and Elecom wireless trackball. It seamlessly switches between two Windows 10 PCs and displays an extended desktop on two 23" Dell HD monitors. No complaints. Especially nice that it comes with all the necessary cables and my favorite remote switch. The KVM and its tangled cables are not in the way, and a small remote control for switching between the CPUs is nearby. KVM, cable and remote control are all of good quality. The KVM is housed in a steel box that is heavy enough to hold plenty of space. I think the next addition will be a powered USB expansion box that plugs into one of the KVM's two expansion ports, giving me unlimited USB ports to connect additional accessories I want to share between two computers. Buy one, you will be satisfied with it. A limitation. It didn't want the laptop running on one monitor powered by one cable while my desktop powered two monitors with a graphics card with two display ports. But with the help of a laptop dock, the fact that I had two DisplayPort outputs also allowed me to connect two DisplayPort cables from the laptop - then they all worked perfectly together.
