Very good accessory with good finishes. Once retracted, the boom takes almost no space, it fits perfectly in a backpack. I use it with my gopros is very practical, this is an accessory worth it and that is not very expensive (compared to GoPro accessories). Indeed, to use it with a GoPro, there must be an adapter. I do not board the tripod adapter screw as it takes, I recommend rather one where you can clip the GoPro.
