I am crippled and cannot use my hands fully. I need a special keyboard and mouse when using the computer. Both use small nano USB dongles. Since I carry my devices to and from work every day, it's very difficult to get the USBs out of the tower, but since I've plugged them into these extensions, I've had no trouble grabbing and connecting them from any computer / to separate. Every day. I know my situation is unique, but you will find this useful for anyone who needs to remove cords on a regular basis, or those with limited arm strength.
