This was purchased for additional refrigeration storage while camping. Two camp trips in and happy with the performance. For the last trip, it was used to hold the beer on one side and store, within waterproof storage containers, the lunchmeat and condiments. Everything stayed fresh and chilled. In fact, after arriving home from camp, I placed all cooler contents but the beer in the fridge. I left those until the following afternoon when I returned home from work. They were still ice cold!
