Dekindy I also have a mirror similiar to that one and it is made by Sprintech but it is also larger and swivels, the mirror has a the socket I think, and the the part that mounts into the bar end has a ball or vice versa. They work pretty well and are easily adjusted, because of the semi covex shape of the mirror objects (ie) other riders and cars are closer than they appear and that takes a little gettin used to otherwise its great.
