One-line verdict

For espresso users who want built-in scale dosing plus the quiet Mignon motor, it adds weight-based repeatability the Specialita lacks while keeping low retention, though it’s pricier than the DF64 Gen 2.

How it compares

vs Eureka Mignon Specialita ($430): Libra wins on built-in scale and dosing precision, Specialita wins on lower price
vs Baratza Sette 270Wi ($400): Libra wins on quieter motor and metal build, Sette 270Wi wins on macro/micro rings
