Recommend this over the clamp version if your table top is thin and/or made out of weak material (e.g. particle board).The stand is quite sturdy. Trying to assemble by yourself is doable, however some people may need a helping hand with this.Vertical adjustment is also a bit of a pain, but if you just plan to setup once and forget, it should be fine.Don't worry about the stand being toppled over as long as you understand basic physics.
When assembling, there was an easy to assemble slide-on monitor mount plate for the pair of monitors. This causes wobbling and instability.Do not get with heavier monitors, or if you are a heavy typer, the whole stand wobbles a lot even after dismantling and reassembling to making sure the parts are a secure as possible.
This device is sturdy and saves aton of space.
Poorly designed clamps for the center pole allow the monitors to sag. The clamps are square with a plastic insert allowing the monitor arms to sag up to a quarter of an inch or more. Had the clamps been made out of milled aluminum to tightly fit the bar this would have been a perfect stand.
