This is a cute little box but it didn't work at all for me. There are two issues, the tab key doesn't work and response from both the keyboard and mouse are often delayed. I'm using a Microsoft Wireless Keyboard 3000 and Optical Mouse 2.0. When I called IOGear support they were aware of the problems and said that this KVM doesn't work with wireless keyboards or mouse. My options were to get a new keyboard and mouse or get a new KVM. I sent the KVM back. Since IOGear is aware of the limitation they should state it clearly on the packaging and product description. Instead they wasted my time and that of the returns department that has to deal with the defective product.
