An important note to everyone. To avoid clogging the needle and one-way check valve with coffee grounds, when you place the K-Cup in your machine, press it down with your thumbs to push the BOTTOM needle into your K-Cup. Then use the handle to close the top, piercing the cup with the TOP needle. This reduces the pressure inside the K-Cup, and the powdered coffee grounds will not get blown up into the needle and one-way check valve.
