Husband needs new 1 for chainsaw gas. Got 1 at WM this morning. These designs are getting really STUPID. Taking it back. You have to turn this green collar thingy and then push down on spout to vent it and let gas out. But everytime you let go of spout you have to turn collar again and then push back down. WTH. It is a Black & Decker can. got to be a better 1 somewhere. I will search friday. It was frustrating me so I know husband won't like it.
