Bests & Worsts Reviews from Amazon

I did not buy this from Amazon as I am a Keurig Club member and got it for a little less expensive but let me tell you, it is worthless as others have stated on here. I used it as directed after much frustration I was ready to throw out my $300 Keurig brewer because it just refused to descale using this. In fact, I went through 2 bottles spending around $40 ! Then someone told me to try white wine vinegar, full strength with a triple rinse after. I was skeptical but I did it and Viola, my beautiful brewer is now making wonderful tasting, no vinegar smell, coffee several times a day. I plan on doing this about every 3 too 4 months at a cost of oh, $1.50 a bottle, I use the good stuff, lol and enjoy my Keurig. So do yourself a favor and DO NOT PURCHASE THIS PRODUCT every other item from Keurig I have ever purchased has been Top Notch, but not this one, consider yourself warned and if you're in the neighborhood, stop in for a nice cup of coffee.
