This is a great Littel accessory for a desk to give yourself some vertical space. The only issue is the way the tension portion that holds the item to the back of your desk is about 3 inches deep. So you need a lip of at least that depth to be able to attach this to the back of something. It will not attach to the back of a flat surface or something with a small overhang.

Installed this under my desk to help organize my extra cables and connective docks. Easy to put together and install!

I like this under the desk shelf. I bought it because I was hoping to remove some of the clutter from the top of my desk, to give me more space. This allowed me to store necessary computer accessories and cords under the desk and out of eyesight. It was easy to put together and feels pretty sturdy. I would recommend this shelf if you have a need for it.
