Grinder Setting Dial for Eureka Mignon | Solid Aluminum Knob | Dial in faster. Repeat grind settings. Easily switch between beans and brew methods. Make precise adjustments every time.

This fits perfectly on my Eureka Libra GBW. Install is super-easy. It is excellent quality. Makes it so easy to adjust the grind setting compared to the factory knob. I 1000% recommend this! As a side, it would be awesome if Aro offered anodized colors.

I saw a video with this addition to somebody's Eureka Mignon grinder and when somebody else asked about it, they linked here. I had to go get one. I've loved my Mignon Facile grinder, but the one frustrating element has been the tiny hard-to-fine-adjust fineness knob. Making a really small nudge can make a noticeable difference in grind, but it can be hard to make such a small adjustment with the small knob. This new knob is larger and also shows the degree of adjustment more clearly and granularly on the much larger included indicator that surrounds the hopper. I've found it far easier now to make exactly the adjustment I need to get from, say, slightly too coarse so that I'm getting a 17 second shot to just right in the 25-35 second range. I can more precisely move it the right degree to get to my desired result. Besides the great increase in functional utility, this mod is solid, made out of a quality painted aluminum that feels nice and will last along with this well-built grinder. It also looks great. The printing on the knob and the large indicator is attractive and clean and easy to read. It makes the grinder look a lot better. I've paired it with a single-dosing bellows attachment that replaces the big bulk hopper and the whole thing looks great. There are replacement knob projects available on the various 3D printing model websites. I've tried two of those and they looked OK, but those tend to slip over the existing knob and require attachment of a separate arrow to point to the coarseness number. I was never able to get the slip-over knob to securely attach -- rather, it would sometimes slip and make adjustment uncertain. Also, the plastic isn't as solid and doesn't look as nice. This alternative aluminum upgrade uses a complete replacement for the knob so it won't slip. It turns the grinder mechanism exactly as the original knob, but with the larger visual and easier control. If you have any of the Eureka Mignon models that are compatible with this upgrade, I highly recommend it.

Very pretty and functional upgrade for my Eureka mignon facile. Gives myself a number for each coffee bean. Also gives the grinder a more premium feel. Install only takes about a minute, but you will have to re calibrate the 0 point on your grinder whenever you clean your grinder now. Also, you’ll have to dial in your beans when you first install this. Nate answers all questions right away. For that, and the high quality, I will give it a 5. In regards to the aluminum. I don’t doubt it is aluminum, but it feels like the faceplate is plastic. So I wouldn’t buy this solely to get an “aluminum look” to match the aluminum body of your grinder. That said; the lazer engraved numbers are likely higher precision and class than the competitors, and the dial itself is certainly aluminum. I like it and am having fun playing with the settings.

I returned it because it does not give you the full grinding range. The product is well-made, and I was very unhappy that I had to return it. I use the full range of my Mignon grinder, all the way from ultra-coarse for cold brew to ultra-fine for Turkish, and the gear ratio on the small knob is not fine enough to reach these two extremes. It's simply not possible to use this to get the full range of grind adjustment. If you only switch between espresso and drip I'm sure it's a great product, but it did not work for my use case.

This is just a perfectly designed piece of gear. Fits perfectly - nothing to glue on or change; made of high-quality materials (metal knob), and most importantly, makes dialing in a shot with this grinder much much easier. Was about to return my grinder out of frustration but glad that I kept it. On top of that, ARO has made a very easy to follow instructional video that you simply watch (no wasted paper instructions). A++

Which is your ability to measure and replicate a grind setting. This mod is tight fitting, and has a nice metal knob. It does enable repeatable grinds. I’m able to go to 20 (quite fine) for one of my espresso blends, and then 70 for a reverse brewer I have, then back to 20 and still get a 27ish second extraction on my gaggia classic pro espresso machine. This showcases the use-case for this mod; if you switch grind settings often and need to be able to go back. This does not come without some minor flaws though. While the knob and dial plate is metal, the dial housing is plastic and the dial gear/base (not viable) is obviously 3D printed. I think the cost of this mod is a bit too expensive. Regardless, it still may be worth the added functionality. This mod kit pays for itself by saving me beans from dialing in. Is it worth it for you?

Great quality and fit as expected from ARO. Packaging was a nice touch as well as the instructions for ease of use. This is absolutely required for a eureka mignon zero and is pure value for money. Your grind quality will thank you.

I was originally going to look for a 3d printed version on Etsy, but Im so happy I came across this. It is way more professional looking and feeling! It looks like it could have come stock with my Eureka Mignon Silenzio. Dialing in the grind size for espresso has never been so easy. Im no longer scared to try multiple types of different beans at once, since I can easily switch back and forth.

Great upgrade to my grinder

A little expensive for what it is, but it's very well made so I can't complain too much. The dials that ship with most of the Mignon grinders are very difficult to use, especially in small increments. This completely fixes that problem and looks great on the grinder. It fits like it's a factory-made accessory.

De standaard dial op de mignon zero is klein en moeilijk af te lezen. Kleine aanpassingen zijn hierdoor moeilijk. 2 upgrades mogelijk: deze van Aro of de Eureka king size dial. De kingsize van eureka vind ik minder duidelijk en met dat plakstripje… neh. Deze van Aro past perfect, met installatievideo doe je deze upgrade in 2 minuten. Knop draait mooi, fijne grote schaal nu, perfect afleesbaar. Geheel voelt solide aan en ziet er naar mijn mening top uit. Mignon grinder trouwens ook een dikke aanrader!!

Bien que certaines parties soient en pla imprimé 3d, la qualité est très bonne et le rendu une fois installé fait très qualitatif.
