I was about to descale my Keurig. I looked up solutions I could mix and read about them. I'd bought this when I got my newest Keurig. So, I used it.

I will always buy this product for my Keurig. Not only did it work well, but it allayed all my worries about ratio, mixing and such. Super easy. And the online video showing me how to use it with my new Keurig was well done.
