The working size of this cooler is 4 12 oz cans. a 32 quart cooler that keeps 1 quart or so cold. If you need to transport something that must stay cold then this is for you. This wasn't for me. I just wanted a functional cooler. My goal was to fabricate a better cooler in a custom size.. this book didn't really help beyond teaching me about heat exchange. I'll use his ideas to build my custom cooler but I won't have side walls of 8 inches or more.
