Query: Horrible - A waste of money!!!

Don't buy this stuff if it's the last dishwasher detergent on earth! Planet Inc. should be ashamed of themselves for selling such an awful product. It wouldn't clean, wouldn't dissolve (regardless of the water temperature), and although I attempted to use it up for other cleaning jobs (kind of like a scouring powder), it did nothing but make a mess.
