Review on EleTab Dual Arm Monitor Stand: Height Adjustable Desk Mount for 17-32 inch Computer Screens - Holds up to 17.6 lbs per Arm by Matthew Mrspeach

Excellent weapon. We installed 2 32 inch Dell monitors and it holds them great. Release the tension as needed, and they can be placed in place and left where we want. The cable channels on the temples are a nice touch to keep things organized. I know it's a small thing, but it means a lot to me because it shows that they were careful in general technique. The kit includes two Allen keys. A heavier one for adjusting the arm tension and a smaller one for the Vesa mounting screws. Since you may need them from time to time, they've added a hex hole on the back plastic cover of the desktop mounting bracket for each one for convenient daytime use when you want to adjust or replace your monitor, and they'll be right there! Fantastic also comes with both sizes of Vesa screws. Similar to the latch on the hand vesa plates, it never disengages accidentally, but instantly when desired.
