One-line verdict

For minimalist espresso users who want the smallest Acaia scale with upgraded waterproofing and faster Bluetooth, it improves on the standard Pyxis while fitting tighter spaces than the Pearl S, though the platform remains tiny for pour-over.

How it compares

vs Acaia Pyxis ($135): Pyxis Pro wins on waterproofing, faster Bluetooth, and battery, Pyxis wins on lower price
vs Varia AKU Mini ($95): Acaia wins on premium speed and app depth, Varia wins on lower price and compact size
