Can you tell me what is the difference between model 80 R 11, 80 R 08B AND 83 R 01? – From Bernard St-L.

Those are not model numbers; they are stock numbers that vary by how the product is packed. All stock numbers that begin with “8” denote cases of our original AeroPress coffee and espresso maker so all of the stock numbers in your question denote cases of our original AeroPress.
