I hated this stabilizer the first week I had it. Was originally purchased to use with my Iphone 12 Max Pro and my Sony a6000. I have never had a stabilizer and have had some balance issues. After doing this, the device was still shaking/vibrating heavily in certain positions. Came across a random comment on a YouTube video that suggested slowing down the engine with the Moza Master app. I did this by resetting the settings from 26:75:86 to 16:60:65. This helped a lot with the vibrations and now the gimbal seems to work as advertised. I have yet to test using the gimbal control app, but I am much more hopeful that my purchase was a success. TLDR: Take some time to properly balance your device, and if you're still having trouble, consider updating the firmware and fine-tuning the motor speed parameters.
