Review on 📸 SMALLRIG Super Clamp with 1/4" and 3/8" Threads for Enhanced Camera, Lighting, and Accessories Mounting - Ideal for Cameras, Lights, Umbrellas, Hooks, Shelves, Plate Glass, Cross Bars, and More - 735 by Missy Yang

I bought two of these Chinese made clamps and surprisingly their quality and finish remind me of American made quality levels! Closing and opening is very smooth, with no visible play during operation. I used to use the typical C-clamps that always slipped off the round PVC tubing I used for our office chairs (due to cheap chairs that slowly go down in height. Typical government-sourced materials). With these curved clips, it secures the pipe quickly and without any slipping. I highly recommend these brackets!
