🪶 Real-World Notes (User Feedback)
While many users report excellent grind quality and consistency, some have noted minor issues, such as:
-
Spout angle sometimes slipping from set position.
-
A few users find dial-ing in shots takes patience on certain bean types.
That said, several home baristas praise its fast, fluffy grounds and workflow experience — especially compared to entry-level grinders.
