This is a set of two magnetic mounts used for the DJI Osmo Action 3, 4, and 5. They can be used without any difference from the genuine products. Of course, they can also be used for hard shooting, such as attaching them to a motorcycle. There is no wobbling or play after installation. I personally use camera accessories on a daily basis, and I only sell items that I think are good. 100 yen off when purchased with other camera accessories. Thank you. #DJI #Osmo #Action #Mount #Magnetic
