If you read this post, you'll know that I was hesitant about getting "cheaper" dishwasher gel. I had been using Palmolive, and bought Great Value brand out of necessity for the budget.
I've been using it for about a week now, and quite frankly... I can't tell a difference from the Palmolive stuff that cost more! I use the same amount of the Great Value brand stuff (I eyeball it to match the dirtiness of the load) as I did the Palmolive, and the dishes get just as clean. I haven't noticed any "film" on anything lately - that sometimes gets on a scraper or a measuring cup, not on everything, and it wipes off with a towel - but I don't know if that's the refilled rinse aid or the soap.
I guess now I need to check out the price of the powdered stuff and see if I can reduce my expense even more and still maintain clean dishes! Oh, but I need to use up what I have first.
