I don't remember if anyone has addressed this product yet or not so I figured I'd give a review. i have been using Premiere professional dishwasher powder for a few years now and am very pleased with the results. I prefer chlorine based cleaners. Well I've been seeing Ultrashine at Dollar Tree for a while now and decided to just get a box to try. The ingredients say it has sodium dichloroisocyanurate dihydrate, which I know to be chlorine. I've done two loads with it so far and it has cleaned well. The dishes don't feel etched, more of a "velvety" feel like when I use JetDry. I opened the door when it first began washing and could smell the chlorine in it. I don't know if I'd use it all the time but in a crunch it works just fine.
