Summary
At $180-$199, Reddit's espresso community says it outperforms electric grinders costing $1,000+. For anyone willing to hand-grind, this is the most performance-per-dollar option in the entire espresso grinder market.
The Libra adds a built-in scale for grind-by-weight precision — the most accurate way to dose espresso. The updated version now sports 65mm burrs, making it one of the most capable grinders under €700.

Our take
The J-Ultra is the open secret of the espresso world — hand grinding sounds like a chore until you taste what it produces. Multiple Reddit users with high-end setups swear it beats their expensive electrics.
If you care about shot-to-shot consistency and don't want to fuss with a separate scale, the Libra's integrated weighing system is a genuine game-changer that serious home baristas love.
