This rubber ring fell out when opening Benro Cyanbird tripod. Is it important? I just bought the Benro Cyanbird tripod. When I opened it out of its packaging, a small rubber ring fell out. It has broken in one place. Does anyone know if this is important to the tripod or was it part of manufacturing/packaging? Note: I bought it with the video and foto head, as pictured. submitted by /u/werewolf_bar_mitzvah …
