Free Your Hands¡¿The coffee grinder electric provides 2 automatic speeds: "1" for slow and "2" for fast. They allow you to free up your hands to do other things while grinding, especially when you are in a hurry. Lock the lid after pouring, turn on the switch, and you can easily monitor the consistency of the grind through the transparent lid. ¡¾Effective Flavor Release¡¿ In addition to the automatic mode, the electric coffee bean grinder comes with a manual mode (P) that helps you control exactly the grind size you need to extract flavor and aroma effectively. Grind your own coffee beans and enjoy more flavorful coffee. Overheat protection also prevents the beans from burning and preserves the coffee's unique flavor. ¡¾Get Rid of Messy Grinding¡¿With a removable and washable stainless steel chamber, the electric coffee grinder lets you simply pour the ground from the chamber into the coffee maker, then rinse the chamber, no more worrying about cleaning. (Please let the chamber dry before putting it back in the base.)
