As IlBob said, is this a real problem? Yes, there is the potential for an explosion, but I don't know if the risk warrants trying to take this product off the market. We really don't know what the actual risk is, other than propane does a higher pressure which may lead to problems. But without actual data or testing, is this really a cause for concern?

I wonder what was this product advertised to do? And were there any instructions on how to use it properly and warnings how to prevent over pressure? I'm not usually in favor of banning items based on assumptions, unless there was a real danger in normal use and no attempt to warn consumers of the potential dangers or evidence of problems in the field.

I would hope in a well designed system, the seal will fail long before the container strength is an issue. That being said, I still wouldn't use this product because the cost savings just isn't worth it unless I was burning through canisters every day. The few dollars a year I might spend on fuel is just the cost of the hobby. But other people might have a legitimate use for this.
