I have purchased the reusable pods to cut down on the amount of landfill. The coffee grains can go into the compost. It is a little fiddly initially but now we fill all four ready for morning coffee in the office.
We are still working out the fineness of the grains to use and the type of beans. As a tea drinker, drinking maybe two cups of coffee a week, I have had at least one a day since we received the pod.
