I have a large metal shed/building that I work in. Its not insulated and in the Summer it can easily reach 100+ degrees for most of the day. I wanted a small fridge to keep drinks cold so that when I was working outside I wouldn’t have to walk up to my house. Also keeps the dirt out of the house pleases my wife. I knew being placed in the hot building I shouldn’t expect much, but I have been impressed. I don’t have a thermometer in it, but I bet it keeps the drinks around 40 degrees. I am basing this on the drinks being very close to the temperature of the drinks in my fridge in the house, which is kept at 36 degrees. Anyway it has been placed in my hot metal building all summer and keeps my gatorade, coke, and water nice and cold.
