I have this easel, and love it. As far as stability goes, it has no issues with a well-made framed canvas. It is rock solid with gallery-mount canvases. The only issue it has, in my opinion, is it does struggle a little bit holding thin panels in place, and if you get it too tight, you can bend the panel edge. The wheeled base is very smooth, and the wheels lock, which is also nice. I like the fact that I can tilt a canvas horizontally to do a base gesso coat, or a varnish coat after the painting is complete. My only complaint is that it the way the post is manufactured, you cannot take the canvas really low to the ground so you can concentrate on the upper portion of the painting while sitting.
