I think I gave the product four stars after one or two loads of dishes, which were mostly plates and pots. I never expected it to work as well as traditional detergents, so I made adjustments like rinsing my dishes extra, extra well and switching to the normal cycle. I realized that what worked best was two cubes in the light cycle. After having to use twice as much product to wash glasses and silverware, I realized it wasn't me -- it was the product. As the previous reviewer noted, the cubes just don't work well in hard water. I can't wait to get through the last of the cubes so I can switch back to Cascade. Since I have to use two per light wash sycle, it shouldn't take me long.
