This K&F ballhead is sturdy and stable. Ivwas worried that it would not be at this price point. It holds my 400mm lens without droop. The panorama swivel locks without pushing the ball out of position. Happy with product. NOTE: The plate does mot match the plates I use but it is removable and accepted the plate from my old ballhead,

I wish it bent 90 degrees in all directions but I knew it didn’t and am satisfied with my purchase.
