Know well the spouts and the problems - work fine when new, gas (ethanol?) swells the parts, they no longer work. I've had two like that that I've tossed.
Got one that's working as it's supposed to - after two years. Push on the spout, the gas flows, stops when filled - release pressure and it's shut off. No ID on the spout itself but the ring to the can says Scepter, Canada. I recommend it, FWIW,
