MiiCoffee DF64 II Review: Zero Retention, Some Rough Edges

64mm flat burrs, a plasma ionizer and a stepless dial with nothing written on it.

Specifications

Specifications above come from MiiCoffee's published product specifications. Treat pricing as approximate, since Amazon pricing moves.

What it does well

• Near zero retention is the feature, and it is the one that changes how you use a grinder. Switch beans between two shots without thinking about it.
• The ionizer genuinely reduces static clumping, so the grounds land in the cup rather than on the counter.
• Stepless adjustment fine enough for real espresso dial-in, unlike stepped filter grinders at the same price.
• Burrs are upgradable to SSP, so the grinder has an improvement path rather than a replacement date.
• Handles espresso and filter properly from one machine, which the Fellow Ode Gen 2 at the same price does not.

Where it falls short

• The dial has no numbers, so returning to a setting after a bean change means counting or marking. This is the same complaint people make about the Eureka, and it is fair here too.
• It is loud. Not unbearable, and noticeably less refined than the sound insulated Italian grinders in the same bracket.
• Single dosing means weighing beans every time. That is the workflow, not a bug, and it is slower than scooping from a hopper.
• Support comes from a smaller distribution network than Baratza or Breville, which matters if something fails.
• The SSP burr upgrade that shows up in every enthusiast discussion is another cost on top of a $399 grinder.

What owners report

The consistent owner verdict is that it does the technical job at a price nobody else matches, with fit and finish that reminds you of the price. Reports of the ionizer working well are common, as are notes that the stock burrs are good rather than exceptional and that the SSP upgrade is where enthusiasts end up. Version differences between 2.5 and 2.6 come up often in owner discussion, so check which revision you are buying.

Who it suits

• Bean rotators and anyone who buys several bags at a time.
• Espresso drinkers who also brew pour over and want one grinder.
• Light roast drinkers, where flat burrs and fine stepless adjustment earn their keep.
• Buyers who would rather spend on burrs than on a sound insulated case.

Who should skip it

• People who want a quiet grinder, who should look at the Eureka Mignon Specialita.
• Filter only drinkers, better served by the Fellow Ode Gen 2.
• Anyone who wants a hopper and a scoop workflow rather than weighing every dose.
