As an athletic trainer, I use a golf cart to transfer water coolers from the school to the fields. This cooler (3 gallon version), does not stay upright because the bottom is too narrow. When I first bought this cooler, the lid would snap on securely and could be tipped over without spilling. However, after just a few months it no longer seals well, so if it falls over in the golf cart, it dumps all of its contents. I will continue to use this cooler for indoor use only, but I will not purchase any other Gatorade coolers until this design is adjusted.
