Used on a camping trip; Several dents and cracks appeared after installing the second tent on the hammer. After the fourth tent, parts of the hammer broke off. We couldn't even drive the stakes for the fifth tent with it; while rubber is hard on the outside and soft and crumbly on the inside. Once the inside was exposed, the hammer became useless and turned to powder. Do yourself a favor and buy a mini sled. This hammer will not withstand being pounded into tent poles.
