Really good, allowed me to expand the work space and add a second screen vertically while I still have a narrow desk at my work cube.
I have an old Herman Miller cubicle at home and I used these to hang monitors off the door of the cabinet above. May not be the intended use, but they're sturdy and it's working.
Very nice monitor bracket for your cubicle. Large range for vertical adjustment. Also, the width of the hook that attaches to the top of the cubicle is adjustable. I would think it would fit any cubicle size. The bracket is holding up the top monitor in the picture. I have it angled down a little for better viewing. Highly recommend!
