When my burr set arrived, they had noticeable dents/dulling along the edges making the burrs dull along every single cutting surface of the set. I've never encountered this issue with industry standard burr sets from other brands such as Mazzer and Baratza. As a coffee roaster and equipment manager, I am deeply unsatisfied with my product. Since the shipping took a while, I will not be returning them.

However, installation is simple and straightforward. Ascaso's grinders are easily maintainable with a moderately sized tool set. Alignment is pretty easy as well provided that you follow good practices such as not cross-threading the brass threads or overtightening anything.

Overall I'm just disappointed in the quality of the end product of the burrs. Care is NOT taken when producing/shipping them so the steel burrs will dull themselves because they have the chance of banging into one another, dulling the sharp cutting surfaces.
