At the beginning of the design of zeroHero RUl portableE-Grinder, we abandoned the traditional three-section bodyand adopted an innovative All-in-one body design, becausewe believe that grinding coffee beans is a very high-frequen-cy operation, and it is actually very troublesome to disassemble it every time. Yes, so at the beginning ofthe design ofRUl portable E-Grinder, we adopted the fuselage structuredesign of a professional electric grinder with several thou-sand dollars level. Open the bean bin and put in the beans di-rectly. The grinder does not need to be disassembled; youonly need to open the upper cover to finish grinding coffeebeans ,and the operation is simpler and more convenient.
