Verdict: A compelling premium dual boiler when flow profiling is part of the hobby—not a necessary upgrade for everyone.
Why it stands out
The paddle offers direct control over flow, while programmable low-flow phases add repeatability. A rotary pump makes operation quieter and supports direct plumbing.
What to consider
E61 machines need more warm-up time and regular group maintenance. The Bianca also asks for more counter depth and a larger budget than compact dual boilers.
Who should buy it
It best suits experienced home baristas using fresh specialty coffee and a high-quality grinder. Compare all recommended dual boiler espresso machines.
