Product Description Watch the set-up and use video here. This listing is for the dial and adjustment knob only. Grinder is not included. Introducing the ARO® Aluminum Grinder Setting Dial for Eureka Mignon, the ideal solution for achieving a precise and accurate grind setting on your Eureka Mignon every time. Gain ultimate control over your espresso brewing process. This product is designed specifically for the Eureka Mignon series grinders and is durable, reliable, and easy to use. It solves the problem of losing your reference point when switching between grind sizes. You can easily adjust the grind size between espresso, pour-over, and French press, and the numbered dial ensures that you can always return to your preferred setting with ease. No more wasting precious coffee to dial in the grind again. The ARO Espresso™ Grinder Setting Dial and Adjustment Knob is a two-piece tool that is simple to install and will change the way you grind coffee in your Mignon. The grinder setting dial has 100 increments so you can dial in your grind size with precision. The geared grind adjustment knob is more ergonomic and easier to rotate than the stock knob. It uses a 3:1 gear ratio, which means three full rotations of the knob equate to one full rotation through all 100 increments on the dial. This lets you make extremely fine adjustments and get the most out of your grinder. Do not forget to pair it with our ARO Espresso™ Aluminum Single Dose Hopper to complete your set-up for the ultimate single dosing combo. Key Features Solid aluminum adjustment knob: Aluminum is far superior to plastic for this application. The aluminum threads ensure the knob does not strip, your grind setting does not drift, and the assembly is built to last. Magnetic two-piece knob upgrade (optional): Magnetically coupled two-piece design that lets you remove the top plate for cleaning without unscrewing the knob or disturbing your grind setting. The square interface and four-position symmetry ensure perfectly repeatable alignment every time the knob is reattached. Stunning laser engraved aluminum faceplates: Minimalistic design, matte black finish, and precision laser engraved text make the grinder look like it came stock with this dial. Non-marring and non-invasive installation: The faceplates are set into a protective plastic housing that contains the gear mechanism. This protects your grinder from scratches while keeping operation smooth and quiet. Matching single dose hopper (optional add-on): Elevate your single dosing experience with a single dose hopper and silicone bellows that integrate cleanly with the dial for a unified look. Available in both premium aluminum and economical plastic. Magnetic Two-Piece Knob Upgrade Option You can choose between the standard one-piece geared aluminum knob and an upgraded magnetic two-piece aluminum knob. With the standard knob, the knob must be fully unscrewed to remove the top cover plate to service your grinder. This means you lose your grind setting and must re-zero after reassembly. The magnetic two-piece knob option solves this problem. The top section of the knob separates instantly while the lower section remains fixed in place, so you can remove the cover plate for cleaning and servicing without losing your grind setting or needing to re-zero. The square interface and four-position gear symmetry ensure the knob always reattaches in the exact same orientation. No guessing. No re-zero required. If you currently have the dial and standard one-piece knob and want to upgrade to the two-piece magnetic version, you can purchase it on its own here.
