I purchased this because my Keurig my was getting old. For years, I have drank great coffee from either Colombia or Costa Rica and utilized reusable Keurig pods and fill them with my coffee. The DualBrew Pro advertises the fact that you can use their Keurig adapter, unfortunately, you can only use the Keurig pods purchased at a store because there design will not allow the use of the reusable pods. I didn't send it back because I am hopeful that the folks at Ninja will come up with a design for reusable pods that will work in their machine.
