Honestly works on most surfaces, I have a glass desk with 2, 27inch wide monitors with no issues.

Does the job even with my heavier 24" G-Sync monitors which I thought might have troubles holding. Make sure you have a little bit of room up against a wall if you want to prop the two monitors together as the arms go back slightly for the monitors to flush up against each other.

Always had the idea to get one of these in the back of my mind, decided to pick one up and I can say it was totally worth it. Cleans up your setup heaps and has lots of cable management routes for your use. A must have item.

Good size, very sturdy and looks great too

The stand is exactly what I wanted. I am very happy with the strong construction and height of the stand.
