The original Key integrated an 83mm conical burr set into the most compact, space-saving design possible.
The Mk.2 marks an evolutionary step in the development of the Key by introducing significant usability and workflow upgrades while maintaining the same footprint as the original version.
The burrs and mount define the width of the Key, so it takes up a fraction of the space required by grinders with burrs only a fraction of the size.
Home espresso is a big investment, and we want you to be 100% in love with your new setup. That's why we offer 30 days to return your machine if it's not the right fit. While return shipping and a small restocking fee are your responsibility (unless there's an issue with the machine, in which case we'll cover everything), we'll make sure the rest of the process is smooth and simple.
In-stock items ship within 1-business day.
Free shipping on orders over $75. To be eligible for free shipping, the final order amount, after applying any discounts, including rewards points, must exceed $75.
Returns are accepted up to 30 days from the date the order was delivered. Smallware items must be unused. Open Box and Certified Pre-Owned are non-returnable.
