YESDEX Monitor Arm: Single $19.99, Dual $39.99 Delivered (60%-65% off) @ AUSELECT AU

I bought the dual Heymix from Amazon for my Dell 32" and I wasn't happy with the level of stability. Typing (on a standing desk) caused it to shake just enough to make me feel uncomfortable.

I returned it and picked up a Prism which is much sturdier.
