One-line verdict

For premium pour-over enthusiasts who want OLED clarity, flow-rate tracking, and beautiful design that matches Fellow grinders/kettles, it excels at visual brewing guidance but is overkill (and too large) for tight espresso setups compared to the Acaia Lunar.

How it compares

vs Timemore Black Mirror Basic 2 ($65): Fellow wins on premium build, OLED screen, and app integration, Timemore wins on price and espresso compactness
vs Hario Polaris ($89): Fellow wins on flow-rate display and modern interface, Hario wins on slim portafilter fit and lower price
