One-line verdict

For end-game espresso and pour-over users who want the absolute pinnacle of speed, waterproofing, and app integration in the Acaia lineup, it improves on the standard Lunar with faster Bluetooth and refined modes while staying the premium benchmark the DiFluid R2 Ultra and Timemore Black Mirror Ultra can’t fully match.

How it compares

vs DiFluid R2 Ultra ($155): Acaia Lunar Pro wins on flagship build, waterproofing, and ecosystem depth, DiFluid wins on price
vs Fellow Tally Max ($235): Acaia wins on espresso drip-tray fit and pro modes, Fellow wins on OLED visuals and aesthetics
