Three stars. The gimbal is very smooth-running and aligns the camera perfectly by itself. However, to use it with the GoPro Hero8, you'll need to replace the attachment at the end of the stand with a tiny screwdriver that's not included. After installing the Hero 8 camera, the app does not support or connect to the GoPro Hero 8, so the stylus has no control over the camera. Again, the buttons on the Humble don't control the Hero 8 due to the lack of in-app support. Very frustrating and apart from being an expensive selfie stick it's useless when the camera is out of reach where you can't reach the camera buttons (because the gimbal buttons aren't compatible).
