I've never seen it, or heard of it. It raises a LOT of questions, tho. Did humidity cause inflation? Did it get wet? Or was there something wrong with it from the start? Did it fully inflate, or only partially open/partially inflate (which would maybe explain it deflating)? Those of us who use these trust them to do what they promise, and our lives may depend on one someday. Hope if you find any answers you will follow up here and let us know.
I'm curious whether this is an automatic, or manual inflater? I think before I could trust it, I would buy a couple of cartridges and test it. Good luck.
