I have a new keurig coffee pot and it has 5 prongs that are to poke into the the top of the capsule. The top of of the capsule is plastic not foil. The water runs out of the top of the machine all over the counter so I am not getting coffee of course. I tried 6 capsules and it happened with all 6, so I had to give them all away. So for me I will now avoid capsules with plastic tops,just a problem with the pit and plastic topped capsule
