Finish Powerball Tablets Failed to Clean Dishes

I bought Finish Powerball tablets and have been using them in my dishwasher for two months, but they are not doing the job. The dishes come out very dirty and with a lot of gunk on them. Even on the heavy-duty cycle, the results are the same even after cleaning the dishwasher and adding more salt. Both the 110-count and the 30-count packages were a waste of money, and now I have to wash my dishes by hand. I also bought the 30-count package when it was on sale, but I now wish I hadn't. I am so angry and upset about the low-quality product that cost me time and money. I won't buy Finish Powerball tablets again, and I'd tell you not to either. The manufacturer should take responsibility for producing a subpar product.
