I don't believe the claim unless the author lives somewhere with near-zero humidity all the time. People use these frequently for homebrew ("keezer" a la "kegerator"). The condensation is a frequent complaint. If you leave the walls of your fridge wet for months at a time, they will mold. It's cold, but not so cold that no molds can grow. And sponging out a chest freezer full of food is a giant pain in the ass because of, you know, all the food.
