I use it to quickly switch between work and home PC. I'm making a simple transition between a shared keyboard, mouse and monitor. There is virtually no lag when switching between computers. Since the device isn't powered, it can't support many more devices connected for sharing (for example, I have a wireless dongle for mouse and keyboard, leaving the front USB port free. Tried the camera through to use, no dice (but I didn't expect that to work either.) Maybe a powered USB can push through, but for the price and what it's supposed to do, it works well.
