I have a DJI mini 2. They fit my controller. They're not much longer than the ones that come with it, but they give it a different feel. They do not fit into the cutouts on the bottom of the controller. I photographed them next to the stick that came with the drone. One is as long as possible and the other as short as possible. There are many reviews of how the threads are reversed. This is necessary to pull the silver and gold items together so they don't come loose. Overall a good quality product.
