One-line verdict

For espresso users who want the quiet Mignon motor plus a digital timer and dose-by-weight, it adds repeatability the Silenzio lacks while keeping low retention, though it costs more than the Libra.

How it compares

vs Eureka Mignon Silenzio ($410): Perfetto wins on digital timer and scale dosing, Silenzio wins on slightly lower price
vs Eureka Mignon Libra ($390): Perfetto wins on stepped precision and timer, Libra wins on built-in scale alone
