Received the Duo few weeks back. And even though I thought I would run some back to back tests, I am too lazy for that and I already like the taste I get from the Duo. I will miss the size, the lower much smoother noise and the anti popcorn disc of the Zero though.
Single owner, received it sometime in March-April 2021. Original box and accessories included.
Used for 2-3 espressos a day when I’m at home.
I prefer collection from London SE23 or can bring it somewhere if it’s not too far.
Price £390 transferred (or cash).
