What I like: 1) Can be clamped or screwed and socketed. You'll immediately see that this is a solid and reliable multi-monitor solution. 2) Easy adjustment of "gas tension" in the brackets. I never feel like they don't stay in place or move around as freely as I need (which is quite a lot since my work requires 3 separate monitors and my desk isn't big enough). And a thoughtful design that allows you to keep the necessary Allen keys TOGETHER with the product and not lose them on the table or in the trash. 3) Ability to hide wires, long arms. Nice design! What I don't like: 1) The hands are bulky. They run at angles that make them less intuitive and take up space that I think could be saved with a better design. 2) If you place your monitors close together, don't expect your desk to be flush with the wall. In order to keep the monitors far enough away from the face, the arms have to be bent backwards, i.e. bent into the space behind the clamp, or pinched the block in a way that is very awkward. 3) Shame on me but I figured they could lift it higher. Be sure to check your measurements in the center of the screen - they're honestly not big enough for my adjustable desk (I'm 6ft tall). You can sit, but standing is a problem. Overall I'm happy with the quality but disappointed with how much room these hands take up. I wish I had paid more attention to the required corners and layout of my office.
