I love using the My K-Cup because I much rather use my own coffee/ the issue I have is I brought a New Keurig coffee maker K80 and I can't get the universal to work properly in it. I've received a different version of the my M-Cup (the old gray version) and will try this one in the new machine. Please don't get me wrong I've never had this issue with any of the Machines I've brought before. I got a different style keurig that I don't usually buy and I do wish I had stuck with the ones I'm use to. I will give the new k cup a try.
