Review on SOOYEAH Isobutane Canister Function Backpacking by Aaron Ward

I have several of these mini camp stoves and burners for our scout squad. We have used cannes piercing tools in the past to be able to smooth them out as they take up quite a bit of space after use and we want them to be recycled properly. With this cool device, I can now take butane from the large canisters in the club's warehouse and fill those canisters even if the adapters don't fit. This little device, which comes in a nice zipped protective case, converts from a store-bought large jar to an empty little round canister that we take with us when we travel.
