Bests & Worsts Reviews from Amazon

Really disappointed that these K cups do not work with my keurig. The ad and the booklet that came in the box clearly shows the k200 being compatible but I get a "this pod wasnt designed for this brewer" error message. I noticed that other reviewers mentioned they received a little purple piece which is supposed to be installed in the keurig machine. I did not receive that piece in my box and my box was sealed. Per the other reviewer, that piece makes that error message go away. Unfortunately it doesn't look like they give you that piece anymore.
