At least the top is flat, unlike the similar stand I returned to Staples, which my monitor rocked back and forth on.

I think it's just fundamental to this design, that it's not going to be perfectly stable if you have a super large monitor.

I'd say, if you plan on using this with something above a 27" Monitor to try it out in the store first, or consider a model with feet on all four corners. My monitor is light, so I'm pleased. I'm giving it -1 Star because although I feel the quality is good, it could be made stronger to work with even heavier monitors.

Solid, Keyboard tucks underneath, ventilation holes

None really. It does what is is supposed to do

Great product. I think that the previous reviewers comments refer to the older version of this stand which was indeed springy. This is a solid unit. I have four of them and I am ordering my fifth. I use them for holding up monitors or laptop computers. I close the lids on my laptops and use external displays on single post three monitor stand. With the lid closed, the laptop slides underneath either of the side monitors. I then tuck the external keyboard under the laptop(s) when not in use.

Love the rubbery surface and the depression for holding pens. Give me a place to slide my keyboard to free up some desk space

This stand works like mounting your monitor on a spring. The metal used is flexible therefore when any vibration occurs (ie someone walking by my desk or even typing to hard on your desk) your monitor will start swaying forward and back. This can last for as long as 15-20 seconds.

To make this monitor work for me I prop my second monitor against the monitor on this stand to absorb the vibration and it's ok but I would stay away from this monitor stand.

10/10 for style, 1/10 for design.
