The concept of this machine is what coffee drinkers need. Choice between pods or grounds? Yes, please! But the pod adapter on this does not work. Ok… truth: IT ONLY WORKS WHEN YOU MANUALLY HOLD DOWN THE LID. Otherwise, it pops open due to the forced pressure, and error beeps occur. Tried at least 20 brands so far, an none work without the manual hold. Inconvenient. The other features are amazing.
