Query: Makes mediocre Coffee

Like others, I found that it has its own "ideal" pod size - others are a compromise. But what is really disappointing is that the Coffee it makes from Melita (the pods I received with the combo offer from Amazon)and other non-JV pods, such as Senseo, is so ordinary yet so expensive. Stick with a good vacuum-insulated carafe coffee maker.
