I am extremely satisfied with the after-sales support team that rendered help with my assembly despite my fault for not reading the manual properly. (Didn't know that I need to loosen the screw in order to screw the main frame into the screw thread)
Assembly: 10/10 (Ease of assembly)
Sturdiness: 10/10
Angle: 10/10 (Quite many pivot points)
A bonus feature is the cable management that comes in built with the stand.
Did not manage to test out the dual arm. I bought the additional arm for future upgrade when I eventually need dual screen.
