The DF64 Gen 2 delivers exceptional single-dose performance and value, provided you are willing to manage minor workflow quirks.
Get this if you want high-end single-dose performance on a budget, and skip it unless you are prepared to occasionally brush out the chute and manage minor workflow quirks.
Owners consistently praise the DF64 Gen 2 for punching well above its price point, offering near-zero retention and robust build quality that rivals much more expensive grinders. The redesign successfully minimizes popcorning and the plasma generator helps with static, though many users still utilize the Ross Droplet Technique for a completely mess-free workflow. Performance is notably versatile, handling espresso and pour-over with ease thanks to the stepless adjustment.
However, the grinder is not without faults. The original dosing cup holder receives frequent criticism for making direct portafilter dosing messy, prompting many to adopt 3D-printed accessories. Clogging can occur behind the declumper—particularly with dark or oily roasts—and early models featured a failure-prone plastic power button that manufacturers have since upgraded to metal. Maintenance is generally low effort, though clearing the chute and occasional burr checks are required.
