Review on 2-In-4 USB 2.0 Switch Box - SGEYR Metal, One-Button Swapping & 2 Pack A To A Cable For Printer/Mouse/Scanner Sharing Between PCs by Ryan Bennett

This switch is a good idea, solidly built with metal case and supports USB 3.0, but it doesn't work at all with a touchpad. I wanted to use it to switch my keyboard and touchpad between two computers, but the latency on this switch is so high that it takes 2-3 seconds for the touchpad to respond every time I touch it. To be clear, I'm not talking about the time it takes to switch between computers. I'm talking about once you're connected to a computer, this box introduces latency into the connection so that EVERY TIME I touch the touchpad, I have to wait two seconds for it to "wake up". This doesn't happen when the touchpad is connected directly to the computer.It's completely unusable for this purpose, so I'm returning it.
