    Love the height and reach

    Love the height and reach, but took a while to get both screens perfectly aligned. Still, very solid build.

    Sturdy arms

    Works well, sturdy arms. Only downside is the larger monitor wobbles a little if I move it quickly.

    Stacking lets me see

    Great product. The stacking lets me see everything at once without straining my neck. Installation was a bit fiddly.
