I was aggravated with the large number of pods that were unusable, but solved the issue earlier this week. Of the last five or six 4-pack pods I purchased, at least one in 4 were bad and unusable. The stores now have a policy of proof of purchase to exchange them. Thanks for making me angry enough to finally just quit rather than be ripped off. Any yes, the 2-packs are equally as bad about pods that do not work. I'm done. By my guess I have wasted well over $200 this year in bad pods. Lee
