Review: A well designed and engineered, premium grinder - This could be the best espresso grinder out there for travel. Using it with Wacaco Picopresso and loving the resulting cups. Built like a tank. Interesting premium material choices. Magnetic catch cup works like a charm. Ergonomics and work flow is top notch. Best part is the grind adjustment system. It’s a well thought out design and works efficiently. Adjustment clicks are pure ASMR. Minor adjustments are possible for perfect dial in. Grind chamber can be dissembled and cleaned without any fuss. Cons: Heavy, because it is built like a tank. Though the handle, grip and engineering of this grinder is near perfect, hand grinding do need some effort and strength.
Review: Wooow - I love the premium experience of esresso from a fine grind. Its amazing

### ⭐⭐⭐⭐⭐ Review
*by J***U on 23 November 2025*

It's a really high quality manual grinder. It's solid, well-made, and it feels like a precision device. It provides repeatable, consistent grind. Adjustment setting and indication is ingenuous. Retention is typically 0.1g or less. Cleaning with the included blower and brushes is easy and quick. Taste profile is typical of traditional conical burr. With medium or more roast, it really brings out the chocolate test in the espresso. For lighter roast, the profile is an orchestra of complex taste as expected from a high quality conical.
