Bests & Worsts Reviews from Amazon

Easy to use and works great! In the past I'd tried cleaning my Keurig with ACV (horrible if you don't get it all out and it curdles the creamer). I also tried simply flushing with water alone which worked for about two days. This is less expensive than the name brand for four uses, I think it has no smell (someone complained about that in a review...not sure what they're talking about), and my Keurig is brewing faster and actually looks cleaner in the reservoir. The solution is a little soapy in appearance, I followed the instructions, used half a bottle, ran a brew cycle til it said add water (all this involves lots of dumping the cup each time), then I filled the reservoir with water and did it again, then I did just water for a second time for a total of 3 times per the instructions. This is three cycles to empty not just three brews. At the end I dumped the lingering water out and cleaned the reservoir, filled it and the next morning had a great cup of coffee. I personally think anyone who had issues using this either didn't follow directions (as a teacher for nearly a decade I know that's most likely) or are just a troll looking to be a grouch. I use my Keurig 2-3 a day every day.
