Very strong little cage, very good for a GoPro. The filter thread fits perfectly. Only 4 stars because the audio adapter bracket is just really awkward to hang around, I think they could have done better. A Rode VideoMicro with a dead cat on a cold shoe dangles in the camera's field of view, but you can tilt it to the side by wrapping the cable around the camera. Overall pretty excited. Just hope they make one for Hero 9 ππ»
