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. Review: Really nice improvement - wish I'd found it sooner! - 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. ## Features - Repeatable Grind Settings: 100-increment numbered dial gives you a clear reference point so you can record settings, dial in faster, and return to them without wasting coffee - Easily Switch Beans and Brew Methods: Move between espresso, moka pot, pour-over, drip, and French press without losing your reference point or starting over each time - Solid One-Piece Aluminum Knob: Durable aluminum threads resist stripping and help prevent grind drift. Knob must be unscrewed to remove the top cover for cleaning - Precision Build: Laser-engraved aluminum faceplates and an ergonomic geared knob make fine adjustments easier, while the protective plastic housing helps prevent scratches and dampen vibration for smoother operation. - Compatible with Most Eureka Mignon Grinders: Fits models with right-side adjustment knobs. Perfetto requires an extra step to remove the stock knob. King Size knobs require a replacement top cover plate.

Like it was made by Eureka *by J***H on December 4, 2025* 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).
