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 Jay Buford

I use this on my iPhone 8 when I'm recording videos. It keeps the phone level with the horizon and also has zoom and other on-device controls. The only complaint is that it doesn't stabilize up and down movements when walking while filming. Correction. I wrote this review for OSMO Mobile 3 by mistake, then I realized it was about counterbalances. I still love them and when you add extra lenses to your iPhone and use the Mobile 3 they help balance the gimbal.
