I've always used the store-brand liquid detergent, but since moving into my current apartment, the dishwasher just isn't that great and we have hard water, to boot. So store-brand started leaving film and wasn't really getting the job done. I always thought the ActionPacs looked neat, so that's where I went next, and I haven't looked back. My biggest fear is that Cascade will stop making them! lol Occasionally there will be some residual powder left on the bottoms of glasses on the top rack, but it's nothing major, and honestly I'd be surprised if there wasn't since there's no top-rack jet, so that I'm chalking up to my dishwasher. Otherwise it rinses super-clean and my good dishes absolutely sparkle when all is said and done. If you have stainless steel cookware as I do, you cannot do much better in the detergent department. I only have to polish it once a week now because the ActionPacs are so freaking good! They're a little on the spendy side, which I'm always kinda neurotic about, but it's worth it! Hands-down.
