ErGear Dual Monitor Mount Arm 13-32 Inch - Adjustable Gas Spring Monitor Desk Stand with VESA 75/100mm - Heavy Duty C Clamp & Grommet Mounting for Flat/Curved Screens (Holds 26.5lbs) - Perfect for Home Office, Gaming Setup & Workspace Ergonomics

This was exactly what I was looking for as a software engineer doing development with multiple monitors and with a hobby and former business in video production and wedding photography. I needed to stack two 27" monitors (one ASUS VGA27A, and one MSI Optix MAG27QRF-QD). I wanted the bottom one to sit flush on the desk (since I like to lean back and tuck myself under the desk) and the top one to line up with the bottom one but tilt forward so that the screen is perpendicular to me as well while I lean back in my chair. The ability to adjust height and support different configurations with room to spare is a bonus. This unit is very sturdy, easy to balance, and can hold displays substantially heavier than mine. In fact, I had to crank mine way down because these newer displays are much lighter and I was still able to find the perfect balancing point.I spent a lot of time researching and could not find any other product that could stack two displays of this size with this much reach while simultaneously allowing side-by-side options if needed. Note that I also have a very large desk that is almost 31 inches deep and I can pull my bottom display within 12 inches to the front edge of my desk AND the bottom edge of my top display still aligns with bottom display while still having enough reach to tilt forward at the same time. Just awesome.In my opinion, this unit is a steal. At this price (under sixty bucks), I wouldn't hesitate to recommend buying 2 or 3 of them in case you want to setup a 3 to 6-display command central setup. I'm contemplating buying a second unit just to steal the arms (unless I can buy them separately) so I can use them to hold my monitor speakers with a custom VESA adapter mounted to the back of each speaker. There is actually enough room on the pole to mount two extra arms, and my total weight with all things included would still be under the unit's specification.No I wasn't paid or approached to make a review. I am writing this because this product just nailed it.
