The Joss Rock Climbing Cam, sold by Sierra Trading Post and manufactured in Italy is being recalled due to the risk of the devise failing unexpectedly. If you own any of these, do NOT use them. Return them to Sierra Trading Post. Cams are devises that rock climbers place into cracks of rocks to support their weight. But most “rocks” being climbed are mountains, usually with a close to sheer face, making the use of cams necessary.
