Very good finish of the swing arm. The paint is well finished throughout. The mechanics reproach sublime. The cable guide is cleverly integrated. Thanks screw instead of riveted joints can tighten each connection when needed. The connection to the table should be made only to rectangular bodies. Rounded edges make it difficult to make it secure but not impossible. The arm itself is inserted only into the table clamp. Therefore, if one is to vigorously unfortunately sometimes completely out lift the arm out of the holder.
