Miraco Lilfount 5-Gallon

I am leaving a review for the product I posted so I can share my experience. I was looking for the "yeti" of waterers, so tired of changing waterers several times a day during the summer to keep them cool. I experimented. Most of my waterers are two gallons, so I filled the Lilfount with 2-gallons and with two frozen water bottles - the same as my waterers for the comparison. All waterers in the shade. 93 degree day with a heat index of 96. My waterers performed as they usually do, at 3 1/2 hours, water becomes warm. The Lilfount kept water cold for 14 1/2 hours until it started getting warm.
