Review on Enhance Productivity with Mount-It! 4 Monitor Stand: Quad Desk Mount for Multiple Computer Screens, Adjustable Arms, VESA Compatible - Perfect for 19-32 Inch Monitors by Ryan Price

Easy assembly. I chose this product over a similar product as it has a higher bar. I currently only use one monitor but need room to grow. The nice thing is that the other 3 arms articulate neatly behind the monitor, and even with only one monitor it looks good. In general very satisfied. Good value for money even if you don't use all the guns.
