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 Josh Maher

Excellent quality in this extremely niche item I had no doubts it would work great and I did was impressed with the quality of workmanship. I think if you take good care of them they will last for many years. The kit includes 3 counterweights that can be screwed into each other if you need to adjust the weight. Very convenient. My particular setup is an iPhone 11 Pro Max with an anamorphic Moment lens and a DJI Osmo 3 gimbal. The Osmo 3 is a very good gimbal, but it seems to lack the ability to somewhat support the size of the 11 Pro Max . These counterweights work perfectly to keep the Osmo 3 balanced and stable even with a heavy anamorphic lens. I've found that 2 weights work best with my setup, but you may need to experiment a bit to determine the balance of your equipment and the number of weights you need.
