I purchased the K-Cup thinking I would most likely get the best reusable filter from Keurig.I was wrong. The first time I used it, water splatted all over the base of my coffee maker and the counter.The second time I used it, I used less coffee, thinking that I may have overfilled it. Still made a mess.I gave it a third chance with paper towels spread out under my coffee maker. Decided I didn't want to haveto do that every time. I ordered Cafe Cups on line and they work great! Keurig needs to redesign....
