One thing I liked from those Martinson reviews (besides the coffee reviews) was the confirmation (at least for me) that the RealCups are basically a OneCup with the extra shell around them.
That's not a knock against them, I really like the Martinson coffees (and other RealCup coffees) I've tried so far (I'd say about 70% of the coffees in our house now are either OneCup or RealCup based).
It explains why I found the RealCups were diluted when brewed on the 12 oz setting, versus the 9 oz setting I have to use with the OneCup based coffees.
