Unless I'm missing something in the description, I kinda like some of the new gas cans. When I had a regular push mower I used to spill gas all the time. With the spring loaded one you prime it, dump it, and when it stops flowing, pull up and it closes. Slick and clean. No spills. But I've always had a child-like attitude...

Nowadays I have an old riding mower and a regular gas can and perhaps because the filler is so much higher off the ground I have less trouble with that than a regular mower.
