ATEN US224 2 x 4 USB 2.0 Peripheral Sharing USB Switch 2 Computers Share 4 Devices Simple Remote Port Selector Included Supports Optional USB Power Adapter - Windows Mac Linux

This little device is wonderful. I am able to multi-task with two computers! I love being able to change to another PC and by the click of a button the mouse and keyboard function. There are two additional USB ports but I haven't needed them.

I tried this for a couple of weeks and it was just not effective enough for me. I only needed to connect 2 device (iMAC and macbook pro) to share a keyboard and a mouse. Again the product worked as advertised, but it was just to slow in changing from one PC to the other since it had to go through all 4 possible options.The one thing that I did not like was that the cables were extremely long; which you usually complain when too short. I don't have a huge desk, but it just made my desk look junky and untidy. I returned and looking into a software option that hopefully works better for my wants.

PROS-- Compact design.-- The USB wires long enough for most setups.-- The button to switch between the computers long enough to place almost anywhere.-- You can easily wire manageCONS-- The wire for the switch button feels thin and might break if I pull on it.-- There are times when switching between computers were it becomes completely unresponsive and I have to switch back and forth for it come back.-- Software for certain mice and keyboards do not detect the M/K when connected to switch

Works as advertised. Works in the background as it is supposed to. Easy install. Would buy again. Has neat appearance.
