This single-dose grinder delivers genuinely good espresso, fluffy grinds, fast workflow, quiet motor, but it comes with a maintenance tax you need to accept upfront. The chute accumulates grounds on the outside over weeks of use, requiring periodic teardowns to keep it running clean; some units clog completely, others just get messy, and the problem can surface suddenly after your return window closes. If you're the type who enjoys tinkering, the DF64 Gen 2 rewards you with low retention, a clear burr upgrade path, and strong performance on medium-dark roasts. If you want an appliance that just works without regular deep cleaning, look elsewhere.
Big burrs at a small-grinder price, the DF83 slots 83mm flat burrs into the sub-$600 bracket where most competitors still use 64mm. Speed is the obvious win: it rips through an 18-gram dose faster than smaller grinders, and the grind quality delivers for both espresso and filter. The plasma generator handles static, retention stays low, and the Gen 2 version fixed some first-gen quirks. Noise is the letdown, one owner specifically avoided loud grinders and regretted this choice, and you'll need to pump bellows after every session to clear retention. If you want 83mm performance cheap and can live with the decibels and the bellows routine, it's worth a look; if you need quiet operation or a truly hands-off workflow, spend more or stick with 64mm.
