I've only used it a few times, but so far it is doing great. I've been doing the scrape, rinse & load (like the cascade commercial) and only 1 item didn't come completely clean. It was my fault as I had let the pan sit for at least 36 hours before running the dishwasher. It was almost clean, and I only had to use a damp paper towel over the unacceptable area (then rinse). It came completely clean with little effort. I've been using Clorox detergent pellets (1/load) and have had no trouble. I haven't used the Cascade samples that came with it, but I'll give them a try when I finish with the Clorox ones I already have.
