I use to have a couple basic gas cans, they had a screw on nozzle and a cap that went under it to seal it when not in use or beingtransported. They work perfectly, pour easiliy, don't leak and last a good long time. When I went to replace them I found I could not longer buy a basic gas can, just pieces of junk like this that supposedly help prevent spills and leaks but, in reality, much more gas spills and lekas from thees than did from the old metal cans or my old plastic can.This is hard to operate, leaked all over the place when trying to fill something and then the nozzle cracked.If you can find a plain basic gas can, buy it. I've been through a couple other gas can marvels since and they are all just junk.
