Like - Holds 5 gallons of gasoline as advertised. Dislike - It takes forever to empty those 5 gallons of gas. Everything is fine with the button, but there is no ventilation and the gas takes forever. Your hand will get tired before the glass is empty. I can try drilling a hole and installing a screw or some kind of vent valve. I should have brought a jar with a regular lid and vent but I was trying to save a buck.
