Check out the 4-port hub by Omars is a great addition to your computer setup!
The back of the hub has a screw and a soft pad to to cushion the computer as you tighten it to the back. This is where you plug in a USB cable and connect it to the back of your computer. I usually have to bend over and aimlessly attempt at trying to connect my USB cable.
Four additional USB ports available to attach other devices to your computer! It has "SuperSpeed USB 3.0 supports transfer rates up to 5 Gbps. Backward compatible with USB 2.0/1.1."
If you have a long enough cord, you can even attach the hub to your desk and get creative with your setup. The hub has an open enough space that you are able to attach to different computers with varied sizes, especially if you want to hang it on your desk.
The build of the hub is of quality material, and the color is almost the exact look and feel of the silver bottom of my iMac. It also saves space by attaching to the computer instead of sitting on the desk like other port hubs. If you need more USB ports or just hate bending over to try and connect cables to the back of your computer, make sure you grab one for yourself!
