About M2 : Designed to suit a range of settings, the M2 allows the user to bring their work to them, versus having to adjust to a static monitor stand. M2’s articulating arm offers effortless height and depth adjustment for the majority of flat-panel screens available today, accommodating monitors up to 9kg (20 lbs.).
* Note: one small plate is missing. Can easily be replaced.
