Anyone have a recommendation for a reusable k-cup? I have the Keurig K10, and I bought the Keurig branded reusable k-cup, but it's pretty terrible. It leaks all over the place and makes a terrible cup of coffee. I've tried pretty much all the fixes people have posted all over online and nothing seems to works all that well. I still have a few boxes of Gevalia I want to get through before considering switching completely to actual k-cups.
TIA
