The can itself is fine for storage, the issue is trying to pour it. I purchased two of these and they both leak like crazy when trying to pour with the included nozzle, and yes, I used the gasket provided with the nozzles. I had to purchase a siphoning hose in order to be able to transfer fuel out of the can, and it takes longer than it would if I could actually use the included nozzle. Also, it would be nice fi there was an easy way to attach the nozzle to the can for storage.
