Came without instructions. Previous bad reviews popped up in my mind, but . How difficult would it be to use KVM? The answer in this case is VERY. Unless you want to use it with a monitor, a computer, no keyboard and no mouse. Despite online resources, I could not see a keyboard. (wired or wireless) and display the selected input for more than a few minutes. In 10 minutes tuned to input #4 it switched back to input #1 3 times. So I'm bringing it back and am now looking for something that actually works.
