Have bought the telescopic rod for my SJ4000. Unfortunately, the threaded bolt is a bit too long, so I had to ne shim between the camera and threaded insert. Did the part then tried on a ski vacation. Ansich not bad but not good either. Makes a pretty unstable impression when it is fully extended. At 50 km / h on the track to me then was not entirely comfortable. Was concerned that the rod bends. But otherwise ok for the price.
