Hoi Lydia, I have the Bialetti Brikka R 4 T., the one with the pressure relief valve in the middle. My comment refers to this coffee machine. As far as I know, it is the newest machine. Unfortunately, it didn't live up to expectations. Even if there are various films on the net where the machine works wonderfully, in everyday life under normal conditions, unfortunately, it does not. Greetings Rainer

Thank you. And what is the difference to item 13259159 (Bialetti Brikka)?

This jug is still the most up-to-date product.
