This is a nice product; I love it it will switch both monitors, USB, Sound together or individually; It works great with my keyboard and wireless mouse
The biggest con to me is not with the KVM itself but trying to get different PCs to work with it using just dual VGA; 2 of my PCs are fine; But my Lenovo Laptop which has 2 DVI-D only ports and 2 DisplayPorts is a pain.
