The efficiency is too low, believe it or not, China Coffee Network believes anyway. This is the biggest problem for China Coffee Network. If I want to make a cup of coffee, if I use 20 grams of coffee beans to grind, the grinding time can be as long as 5 minutes. When shaking, your hands will still get sore.

The wood base is easy to break, and the grinding plate on the hand bean grinder is fixed on the wood base with screws.
