I bought this two weeks ago. I tossed it in the box of my SXS. Put in the beverages and 16# of ice on Saturday. I looked this Tuesday morning and there was still ice in it. Granted it has been between 40 and 70 here lately this spring. My sandwiches were dry and candy bars hard from being cold in bottom trays. Love it. Likely going to order the smaller one as well. Well made.
