I've always been a user of the tall, square-based "race cans" for fuel. Bought one of these out of interest about 2 years ago, they are all I use now. The sealed spout is great for wrestling into awkward positions without spilling or trying to use 1 hand to direct a hose. And having a real vent means it fills about 5x faster than other EPA/CARB cans I've tried that vent back up the spout (for that painfully slow glug........glug.......).

Empties quickly as promised. Wife is still in shock at the price, though.

I'm 62 years old and these are absolutely the best gas cans I've ever used. I purchased one a couple of years ago, and even though I have several other brands that are perfectly fine, I've replaced all of them with Fuelworx. My only complaint is that they're rather expensive, but the first time you use one, you won't regret spending twice as much as cheaper brands. No more glugging, aerating, or holding the can at odd angles for long periods of time.

If you do not pull the white strainers out of the can spout you cannot fill them without splashing gas back on you. Horrible design. Once I did that they work great. I really like the stackable design, it saves space in my garage.
