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 Gina Clark

In general, this is what I was looking for. I have four 27 inch LG monitors with plenty of space. It's frustrating to level them all; I'm not sure what can be done to make this any easier, but don't expect perfection here. However, I am satisfied. As for my overall star rating: range of motion - as mentioned above, maybe too much. Easy assembly - basically. The fit and finish is not perfect. Read the instructions. Durability - no question. So true.
