I am very happy with this stand. It makes it easy to use my pen displays as a monitor and then put them in a position that is convenient for drawing. See the photos at the bottom of this document for some examples of what it looked like with a 22" pen display attached.

It does support VESA mounting.
The stand comes in several pieces. The package comes with the screws and two hex wrenches.
Putting it together is not difficult. And the user manual is clear on what to do.
You will need a Philips-head screwdriver to attach it to a pen display with the provided screws.
Like all stands and arms thee is some wobble if you press on it. This is normal and was not a disappointment.
However, there is a good range of motion and adjusting so that the bottom edge of my 22" pen display touches the desk helps tremendously in stabilizing it.
Tensiona adjustment
The tension on the arm is adjustable with one of the provided hex wrenches. I turned down the tension to work with my 22" pen display.
The base was surprisingly heavy.
I attached the table with the screws and used the washers in this way because I thought it would be a more secure fit.
This is where the tension is adjusted.
The rotation on the stand goes about +/- 45 degrees
This is about as high that the display can go.
With my 22" display I could lower it such that the display could securely rest on the desk.
It can be tiled back. I was able to keep the bottom edge of the displayt securely on the desk up to 35 degrees.
But at angles greater than 45 the edge of the display could not touch the desk.
Here are some more extreme angles.
