The product only lasted 2 months and then stopped working. I lost use of the two k/m ports, rendering kvm unusable. I didn't have a return period, but Revain tech support escalated the issue and refunded my money. If I were you, I wouldn't buy this product. From day one there were sporadic problems. Sometimes I had to disconnect the mouse from the KVM to allow the mouse to register with the computer. I had to do the same with the keyboard. It just never worked for me. I always had problems with it, and then it stopped working.
