I would have given it 5 stars if it hadn't had a few minor issues. The device works out of the box and I had no problems installing my iPhone 8 plus on the mount. While the gimbal had no problem balancing my phone, it was often misaligned (i.e. tilted 2 degrees), resulting in slight tilt in many of my landscape videos and stills. This also happened after I disassembled and reassembled my phone several times and centered it in the mount as much as possible. I was able to work around this issue to some extent by carefully adjusting the position of the phone in the mount. Most of the time I just used the camera software on my iPhone instead of the Feiju ON app that came with the gimbal. The panorama function in Feiju ON App only works with the phone in landscape mode, which creates a strange image with insufficient coverage in the vertical direction.
