Review on 📷 ULANZI PT-10 OM 4/OSMO Mobile 3 Gimbal Stabilizer Counterweight Balance Counter Weights – Supports 60g, Compatible with DJI OSMO Mobile 3/4 and Moment 1.33X Anamorphic Lens for iPhone 11/Pro/Pro Max by Mark Hamblin

These counterweights work as advertised and are easy to fit. I attached two and was able to move my iPhone 11 Pro to the left just enough to keep the ultra-wide stabilizer from catching on the frame. If I had one wish, it would be two 20g weights and two 10g weights in the set to allow for more precise balancing in 10g increments, which benefits the Osmo Mobile 3 gimbals.
