SmallRig ダブルボールヘッド アーティキュレーティングアーム（1/4インチネジ）#2070B

The knurled knobs tighten down with barely any effort, and the double ball heads hold my monitor in place rock solid even when I bump my desk. Shipping from Vancouver was quick too, which is a nice bonus.

I was a bit skeptical about the double ball heads, but they make positioning my monitor light so much easier. The 1/4’’ screw holds tight and the arm doesn't sag at all, even with a heavier accessory attached.

I needed a sturdy arm for mounting a small LED panel to my rig, and this double ball head setup locks solidly once you tighten the knobs. The 1/4'' screws fit my gear perfectly. Only wish the knobs were a bit larger for easier grip with cold fingers.
