MiiCoffee DF54 Single Dose Coffee Grinder (Black)

Had for about a week, very nice to use, burrs appear to be perfectly aligned out of the box (checked with marker), getting amazing espresso. No issues with static or clumping so far. Have given the chute a quick brush a few times to try and keep the anti static device clean Possible to grind directly into portafilter or basket if you use a funnel and occasionally knock the grinds pile so that they dont back up into the chute. can flip the rubber piece to help. The philips head holding the chute was damaged (presumably during assembly), and in DF64's own video on youtube they mention the screw is very soft, so that may be an issue long term, no idea why they couldnt provide a better screw, and hex matching the other screws and included allen key would have made a lot more sense. Contacted them via amazon chat and they were uncooperative and basically blamed me... Dosing cup - not a very snug fit to my vst basket, so if you shake the cup to distribute the grounds, a fair bit seems to escape to the outside of the cup. fines seem to stick to it, so i tend to grind direct to basket instead. a metal cup would probably be better, can buy df64 one separately but dont think its worth it

I've had this for 3 months now and it's performed great. Simple to use and easy to dial in a consistent espresso grind. It's very easy to clean although when I went to clean it after 2 months of daily use, it barely had any old coffee grinds in there so what you put in you get out which is fantastic.

First thing is the weight. Chunky, really quite heavy. Solid though, no rattles. In operation, this is impressively quiet. Grinds beans effortlessly. The stepless setting will please aficionados seeking precise grinds. Top notch.

Well built and grinds perfect for espresso going as fine as you like! Has some weight to it and the construction is great…..definitely good build quality. No hesitation in recommending although you have to be patient as it takes a couple of weeks to arrive.👍

1. I loved this grinder, it worked very well once dialled in, however within 2 weeks it started to throw coffee grinds all over our kitchen work surface, I think the plasma generator fails or fails to do its job after a bit as others have said. So 5 star for the grinder until it stopped working so cleanly after 2 weeks and then it becomes a 3 star grinder. Maybe I could have taken it apart to try and fix it but don't see that as my job and when I read the instructions it said nothing about required maintenance and actually says do no dismantle the machine. 2. Luckily as I bought it via Amazon even though from a 3rd party seller in Singapore, Amazon customer service was fantastic and the return was processed straight away although I did have to pay the hefty return postage but to later be refunded. It took a while to get returned as I think the 3rd was a bit delayed in doing some of the import papwerwork / processes. Overall put your trust in Amazon customer service though and all will work out fine if you have issues or faults like I did. 5 star for service. 3. My biggest issue is the 3rd party seller firstly made it very clear they were not happy I made contact via Amazon and had clicked I wanted to return it due to fault, they said I should have instead contacted them direct, not sure how, maybe they meant outside of Amazon. They then said despite them / Amazon only suppling a non-prepaid returns label and me having to choose and pay the cheapest method to send it back (UPS), that I should have instead used another 'method' they know, not sure what as I regularly post items abroad and so know how to ‘legitimately’ send things the cheapest way. They then said my 2 week old grinder was scratched and fully working and so I had no right to return it! Firstly it was NOT scratched it was only 2 weeks old and I'm OCD with my kit, but Secondly it was faulty and so I had full rights to return it after 2 weeks. The Amazon listing in fact clearly stating it can be returned within 30 days, mine failed to function as expected after 2 weeks.

Works as advertised and my husband use it 2 times a day at least never complaining. The build quality is fantastic complete solid a lot heavier than I expected and is not very loud when grinding

First grind and coffee excellent really pleased with my purchase

Really good value but not 100% convinced by the quality control, the grinder does grind really well until the plasma generator to control static fails (after less than 20 grinds) then you get more clumpy grinds needing WDT and a messy grinder with all the static making the chaff and fines stick to the machine. The adjustor ring is also veeerrrry stiff and could do with some texture as the shiny metal is slippery so adjusting grind size is annoying. These are small things but if fixed would be a 5 star grinder.

Absolutely amazing grinder for the money. Too bad my cat ate the rubber portafilter holder while I was away 🥹

After a lot of research on which coffee grinder to buy, and after using the Sage Smart Grinder Pro for a few months, I decided to buy the DF54. Since I only use lighter-roasted Specialty coffee for espresso, the Sage Smart Grinder Pro did not work well. It is good for normal medium or dark-roasted coffee purchased from the supermarket, but with light-roasted specialty coffee it often got stuck (choked), sometimes it could not grind the coffee finely enough, and if it succeeded, it was on setting 1-3 out of 60 available (with the internal setting on 3 out of 10 degrees, he couldn't do less than that because otherwise, the conical burr touched one from the other). In addition, it had a huge retention (0.5-1.0g), unacceptable, until I got an excellent bellows by Fused Line (then retention was from 0.1-0.3g without cleaning, but inside the grinder always stays 2-3g of old coffee). However, to get to the point of this review, because of the above, I decided that I don't want to have these various problems anymore and I was thinking about the DF64 or Niche Zero model, which is currently a bit out of my price range. However, in these few months, DF54 appeared and since then I looked at all possible reviews, and concluded that it could be the one I wanted. Even though I came across several negative comments, especially on Amazon, I still ordered it as soon as it was available. Since it is apparently in high demand, I had to wait more than a month for it to be delivered, but that's fine. I've had it for more than a week now and so far everything is flawless. I hope it will stay that way for at least the next couple of years. So far it hasn't had any problems with choking, although I only use various light to medium-roasted single-origin specialty coffee. On average, I grind for espresso on a setting between 12 and 20 of 90 settings, depending on the type of coffee. So it can grind much finer than it grinds now. Retention during the first grinding (new grinder or after cleaning) was approximately. 0.3g, everything after that is practically zero, or sometimes 0.1g, all with a few pressures on the bellows. Without the use of bellows, it is about 0.1g. That's a great result for any grinder, especially after experiencing of using the Sage grinder. With humidity in the apartment between 40-50%, I have no problem with static electricity and the grinder is really clean. It dispenses coffee very consistently, without lumps. It works pretty quietly while grinding, and almost silently without coffee. And when it is without the lid, it does not throw the beans or anything inside out thanks to the anti-popcorn disc. I've seen many people comment in video reviews that the bellows fall off easily, but that's not true. Because the bellows have different sides, up and bottom sides, and the difference is visible from the inside, so if it's positioned as intended, it won't fall off the top of the grinder. In any case, I can't find any flaws so far. I hope it will remain so in the future. In addition to all of the above, I brew coffee on a Gaggia Classic Pro (built-in PID and variable preinfusion, 9 bar springs, and IMS Competition and BigBang baskets), and I can only say that with this grinder, the coffee is incomparably better, creamier, better body than before with other grinders. The conclusion is that this (after ten days of use) is a superb grinder for a very affordable price. And the DF54 grinder's build and look are exceptional. 07/2025 UPDATE after a year of using: After more than a year of using this grinder, I can confirm that everything still works perfectly. A few months ago, I checked for the first time the gap between burrs, and it was pretty balanced. I do a very small correction on one side, but nothing significant. I just need to put 2 small pieces of aluminium foil below the screw of the burr on the upper part of the grinder, that one that had no rotation (you can see it in the picture). But that is normal when using this grinder daily, at least a few times per day. Note: I use only high-quality specialty coffee, light to light/medium roasted, so the coffee beans are slightly harder than regular coffee, but so far without any problems or burr choking. I hope that all remain the same in the future. I highly recommend this grinder.

1 Month Update: I still really love this grinder. Best value purchase for the grind quality you get. After about 1-2 weeks of use, I noticed more static in the grinds, but a simple clean with the included chute brush resolved this and it's back to clean static free output. I've also started to spray my light roast beans, but not necessary for dark to medium roasts. I still love the look and how sturdy yet quiet it is. I also recommend hot starting for grinding to help maintain grind consistency. No clogging issues whatsoever. You can't go wrong with this grinder if you're looking for something for home that provides a quality grind to elevate your espresso journey. Original review: I wasn't one of the early adopters of the DF54, so I had to wait for the next batch shipment to be available so I could get my hands on one. My previous grinder was a Baratza Encore that barely met standards in terms of a good espresso grind (very inconsistent, muddy flavors), which it wasn't really designed for. I've read some of the complaints of the DF54 in terms of the zero point and static issues and I have to say so far I have none of those issues. Maybe they tweaked the manufacturing to address some of the prior issues to improve Quality Control on these latest arrivals. 1. My DF54 right out of the box hasn't had any static issues yet, even when grinding light roasts (which tend to have more static than darker roasts). 2. The Zero Point was spot on. Just turning the dial a hair past "0" was where the gear "chirping" happened, so I'm happy with this calibration. 3. First few grinds had a little bit of retention, but after that and using the bellows, the final grind comes to +/- 0.1g from the initial beans dosed. 4. Some video reviews talked about how the bellows come off too easily from the grinder, but with mine, the bellows are fairly snug that if I try to remove them, the "anti-popcorning" cap slips out with it, so seems everything fits well together. I haven't check the burr alignment on this unit, but so far I don't feel like I need to. For Espresso grinds, I have it set in the vicinity of 20, and my shots so far have produced wonderful clarity for fruity notes, but enough smoothness for flavors like vanilla. Very satisfied with my purchase. I really love the compact design, the quiet operation and pairs well with my Bambino Plus. I'll provide an update in 1 month.

Oggetto di design ..pesante ben assemblato..ero dubbioso sulla macinatura fine per espresso viste le recensioni ..invece ottima resa con filtro a pressione e tacca 10 adesso proverò il cestello IMS con portafiltto vuoto per esaltare la schiuma..caffe in grani dark della Costarica

Tocó jubilar a mi Baratza Virtuoso+, sin embargo no podría estar más encantado. La calidad de construcción es excelente, es robusto, pesado, pero requiere poco espacio. El unico punto donde podría mejorar es en cable, ya que si se siente de una calidad mas baja (Tomando como referencia el cable del Molino Baratza). Pros: - Practicamente 0g de retención. - Se pueden percibir notas en el café con mayor claridad (Espresso y filtrado). - Es rápido comparado al baratza. - Hace poco ruido. - El Ionizador funciona perfecto, no se hace un desastre. - El "Anti popcorn" funciona muy bien, no se andan saltando los granos. Puntos de mejora: - El cable si se ve medio chafa, la verdad. - No viene un manual donde te diga que rango se recomienda para prensa, filtrados y espresso. - El punto 0, no es en realidad el 0, tienen desfase de fábrica. En el mio el 0 esta en el -5. (No es un problema que haga malo este molino, hay piezas impresas 3D para corregir esto). - Si lo pensabas usar para filtrado, puede que no sea el mejor, ya que su muelas estan mas pensadas para espresso y crea bastantes granos finos. (Hay una técnica llamada "Slow Feeding" que ayuda a la uniformidad). Notas: - Toma en cuenta que podria taradar bastante en llegar, el mio tardo casi un mes.
