Works well with the Zhiyun Smooth 4 gimbal. I use it to stabilize both my Samsung Note 8 (in the Otterbox Defender case) and my GoPro Hero 8 (in the Plusz mounting plate) to compensate. . I would recommend a drop of threadlocker on the counterweight threads. This will prevent them from loosening due to vibration.
