Query: $20 for this???

It came bent and scratched. I really should have listened to the other reviews I read before purchasing this item. The top is made of thin aluminum and the bottom is made out of foam. The foam reminds me of the foam used in shoes to cushion them when you walk. It is so cheaply made that it's embarrassing that they charge this much money for it. If they used thicker aluminum this product would be much better, but of course this would cost them more and I have a feeling they don't care about quality. The foam is fine, it's what is needed for insulation, but the bottom line is they KNOW they have a problem with a flimsy product and are still producing a product that is cheap. Well, if I were you, I would not buy this!
