Last year while climbing the screw holding the front point broke while climbing. I reported the issue and BD send me a new screw and front point. Also telling me I should make sure the screw it tightened. I have been climbing on my crampons since and yesterday the other crampons broke mid climb. Once again, the screw holding the front point broke. I had tightened it just two days before and only had three pitches on it since. I climb with them around 20 days a year. Something does not seem right with the Stinger design or this batch.
