I didn't buy this from Amazon but I still had to leave feedback here because this product was sooo bad, We use a lot of Seventh Generation (and Mrs. Meyers and Shaklee's, etc.). We ran out of our Shaklee dishwasher powder detergent so I bought some Seventh Generation to replace it. It left massive amounts of soap scum. To the point where my dishes were cleaner when I put them in dirty! And then I would try to run those dishes in there over again and they were still bad. And then I hand-washed them and the soap scum still wouldn't come off! Suffice it to say, I am all for ecological, but I would never buy this product again. In fact, who wants a barely used box up for grabs?
