Pump pressure consistency

A true 9 bar OPV and firmware controlled pump deliver commercial-like, repeatable pressure, and a simple manual button trick lets advanced users gently ramp down pressure at the end of the shot for softer finishes.

A tuned overpressure valve targeting about 9 bar at the grouphead and a full pressure release system that dumps water to the drip tray at the end of a shot support consistent extractions and immediate, mess free portafilter removal, and reviewers note that unlike many compact machines it does not sacrifice brew pressure or purity for its small footprint.

Pump pressure feedback is made easy with a central pressure gauge that shows whether the machine is hitting the right pressure during extraction, helping users quickly diagnose likely under- or over-extraction.

Despite 15-bar marketing, real peak pressure is described closer to ~12 bar and the system is capped; with proper dosing and grind, users can aim for more espresso-appropriate pressures (around 8–9 bar) while maintaining reliable shot-to-shot behavior.

High pressure system with front gauge favors coarser grinds and easy extractions but trades off finesse.

Pressure feedback is useful in concept and some users find the gauge helps dial in, but precision and reliability appear mixed, with reports of the gauge not working in lower-rated reviews.
