In the 20+ years I've owned a dishwasher, I've always used Cascade. I'm not one to rinse my dishes before loading them, because I figure if the force of the water jets can't rinse them enough, I don't have a powerful enough dishwasher. If I had an extra large or scummy load, I'd always fill both cups with the powder. When the Actionpacs first came on the market, I was skeptical because it seemed the price for the number of uses was high compared to the boxed powder. Then by just using one Actionpac, even on the larger loads, I found that they came out just as clean as if I had used the two detergent cups. I even kept track of how many uses I got from the box as compared to the quantity of Actionpacs and found the Actionpacs came out to be the better deal.
Also want to mention that a neighbor was moving and gave me her other brand of dishwasher powerballs. They just didn't do the job that Cascade can do. Therefore, you can consider me a loyal fan and loyal customer of Cascade! Thank you.
