Review on Keurig Universal Reusable Ground Compatible Kitchen & Dining by Rafael Lewis

. Works great in my Keurig K Cup coffee maker. When I first used it I thought it was the wrong type because it seemed to sit higher in the jar than K cups would normally fit in a pot. You have to pull out the standard K cup holder and replace it with this adapter, and this adapter is slightly higher up the vessel. After experimenting, I decided it should look like this, and it works great when making coffee from freshly ground coffee beans.
