I bought a 35 qt. Englar recently, about 80 bucks less than comparable Yeti. Steamed36 ears of corn about 9-10 am. At about 2:00 pm, corn was almost too hot to pick up out of the box. I had pretreated cooler by pouring a teapot of hot water into it for a short time before dumping the water and adding the corn. Great hot box, haven't used it for cold yet.
