Death Wish Coffee Co. I am a mechanical engineer. The first 2 pods caused the pump to fail and had to replace the Keurig machine. I am meticulous about descaling and needle maintenance of my machines. I then tested the pods on several Keurig machines. A rewired 2.0 to accept generic pods indicated excessive pressure and then deactivated the process. The top and bottom needles punctured the pods and the needles were clean. The upper and lower silicone gaskets were new. The pods were inspected and the coffee was expanded all the way to the top after use. Hot water was introduced into a pod slowly with a glass syringe with the bottom of the pod punctured to the size of the bottom needle. A seal was placed around the syringe needle to simulate the top needle on the machine. The hot water stopped flowing from the bottom puncture point. This would indicate that the grind was too fine or the bottom pad was of inadequate size to keep the bottom needle from clogging..
