The verdict

Why it scored a 79

The MiiCoffee DF64 II brings 64mm flat burrs, stepless adjustment and a single-dose workflow to $399.00, which is why features score 86 and value holds at 80 despite the price. The listing claims under 0.1 gram retention, and an ionizer and anti-popcorn disc address static and bouncing beans. Satisfaction is 86: a 4.4-star average, trimmed 2 points because it has only 276 ratings. Reliability is 76 because the review base is thin and it comes from a smaller importer, not an established appliance brand. The warranty is 1 year from MiiCoffee (55).

Who it's for

Should you buy the MiiCoffee DF64 II?

The MiiCoffee DF64 II is for a home espresso maker who weighs every dose and wants flat burrs without spending $500 or more. At $399.00 it ranks #4 of 10 in our Coffee & Espresso Grinders category. The Eureka Mignon Specialita is the quieter, better-finished pick with a hopper at $549.00. If you want something simpler with a big owner base, the Breville Smart Grinder Pro is $199.95.

What stands out

Where it earns its score

Big burrs for the price. 64mm flat burrs match the Fellow Ode Gen 2, but unlike the Ode, the DF64 II is built to grind for espresso.
Stepless dial. No fixed clicks, so you can make very small changes when dialing in a shot.
Low retention. The listing claims under 0.1 g left behind, and a blow-out funnel clears the dead space.
Upgrade path. The stock burrs can be swapped for aftermarket SSP burrs if you want a different flavor profile later.

Before you buy

What to know first

Warranty is the lowest factor at 55. MiiCoffee offers 1 year of warranty service, counted from the delivery date.
Third-party seller. It is sold by MiiCoffee, not Amazon, so returns and support run through MiiCoffee.
Hands-on workflow. Single dosing means weighing beans every time; there is no bean hopper for grab-and-go use.

Bottom line

Our verdict

The MiiCoffee DF64 II scores 79, a Fair Buy that ranks #4 in our Coffee & Espresso Grinders category, led by Features (86) and Satisfaction (86). Buy it if you single-dose espresso and want flat burrs at $399.00. If you would rather have a hopper, a quieter motor and an Italian build, the Eureka Mignon Specialita (79) costs $150 more.
