MiiCoffee DF64V Variable Speed Single Dose Coffee Grinder

This is my first flat burr grinder. I did a ton of research to find the best fit for me. Something that is affordable and a great value, well built, espresso capable, easy to clean/swap burrs, great range of RPM, reasonably quiet, aesthetically pleasing, and (very important to me) has a small footprint.

Boy, has this grinder aced everything I wanted and then some. The DF64V is at a great price for what you get. It feels very sturdy and thoughtfully designed. I love being able to disassemble the grind chamber without tools. It makes cleaning easy and actually enjoyable. The magnetic shoot is also just great design and makes for quick cleanups as well.

The RPM selection is perfect for a wide range of experimentation. I got the V1 to get access to the 600 rpm, and I’ve had zero stalls so far. Even with some uber light roasts. On that note, the V1 doesn’t have the plasma generator. So, I use RDT on my beans and get very little static issues. No RDT does make for a lot of clinging though.

The motor is whisper quiet. So quiet that I honestly wish there was an auto-off feature in case I think it’s off and walk away for a bit. It does get a bit shrill when grinding, but what grinder is perfectly quiet as it does its job?

I love the design and dark color of this grinder. I was pleasantly surprised how small it was once I took it out of the box. It fits my limited counter space better than I could have hoped. My one gripe is that the grind settings are hard to read on the back side of the machine. If you grind courser for pour overs like me, get ready to tilt and slide this grinder to check your setting a lot.

I know some folks don’t like the wooden stand, but it doesn’t mess with my workflow. I actually love not having to slide a metal cup into a metal bracket. Subtle “grinding” like that just bugs me. The wood is also just visually pleasing to me.

As a bonus, working with MiiCoffee was a great experience. They shipped out my order super fast! I also happened to order an extra set of burrs that I had a change of heart on shortly after ordering. I explained this to the customer rep and they were extremely understanding and got me all set up for a reasonable return on that portion. Having patience and flexibility with customers goes a LONG way in my books. :)

tldr; This is a wonderful grinder at a phenomenal price.

I’m satisfied enough with the grinder that I’ll keep it, but there are some issues to be aware of if you’re considering buying.

Pros
- quiet motor (though kind of unpleasant sounding when coffee is being ground)
- even and consistent grind
- small footprint
- Easy to disassemble

Cons
- Retention is more than I expected. Removing the declumper helped a bit. I was hoping to use this grinder for both espresso and pour over, but with the retention issue, it’ll be a dedicated espresso grinder instead to avoid cross-contamination.
- Stalling issue. Even with the new board, the motor stalls when grinding at the lower settings. This happens even when I hot start with medium roast beans. Now I don’t go below 800 rpm and slow feed the beans.
- A good amount of static/clinging even with 3 sprays of water, especially at higher rpm
- the dial ring (with the number markings) came scratched up

I came from the DF64. The DF64 has lots of flaws, being the first generation, like the chute has a lot of dead space for the coffee ground to stick on. Has lots of static, the collar being the grind level adjustment is very annoying to use. With the DF64V, all the mentioned issued are fixed and dialing coffee is a breeze. I only have the DF64V for just under a month now and it is so easy to work with and produce a great cup or coffee. I can't compare the taste of espresso because I also pair it with an upgraded espresso machine.

This thing is so beautiful in person. I am very happy with how well built it is so far. Only nitpick at this point is that the variable display is slightly off of level (twisted slightly clockwise) and that the display on the variable is always on unless I unplug the machine.

I purchased the DF64V to replace my K-Max hand grinder. The DF is a wonderful grinder with almost no retention when using a little RDT. I have had it stall at 600 rpm with light roasts even when slow feeding so I always grind at 800 for pour overs. I understand that the new model coming out starts the rpm at 800 anyway. No problem there. The consistency of the grind seems amazing. It’s almost totally quiet when running (until it’s grinding of course. The magnetic shute is fantastic. Very happy
