Query: Total rip off!!!!

I bought the 40 ounce version on Ebay with free shipping for $28.00. I was expecting MUCH more for the high price. The Kleen kanteen is NOT insulated at all. If you put something cold in it, expect it to get warm really fast. If you put hot stuff in it (like me), expect it to get cold fast. Expect to burn your fingers every time you pick it up. Expect to burn your inner lip on hot metal ever time you take a sip. The steel is VERY thin. I expect that if i dropped it, it would certainly dent.This product is honestly worth about 6-8 dollars. If I bought it from their website for $28 AND paid the high shipping cost, I'd be enraged when the product arrived. It's simply way too expensive.
