This all-metal workhorse grinds espresso beautifully and runs quieter than most competitors, but the stock adjustment dial is the size of a shirt button and makes fine-tuning feel like defusing a bomb in the dark. The 55mm burrs are excellent, the build is tank-like, and the compact footprint fits under cabinets, but displays fail after six months for enough users to matter, and true single-dosing requires an aftermarket hopper and bellows the factory should have included. Buy it if you enjoy tinkering with a strong modding community behind you, or if you'll use the hopper as designed and can live with 2g retention. Skip it if you want plug-and-play reliability or resent paying $400 for a grinder that needs fixes out of the box.
Niche's flat burr single-dose grinder pairs 83mm burrs with the brand's cult following among espresso nerds, promising the clarity and consistency flat burr devotees chase. The catch is stark: almost no one owns one yet, so you're buying on theory and brand trust, not the field-tested proof that exists for the conical Zero. If you're comfortable being an early adopter and value the Niche workflow enough to take that leap, the fundamentals look sound. If you need to see a grinder survive a few thousand shots in real kitchens first, wait six months and check back.
