Who it suits
- travel, camping or a desk setup where there is no socket
- one or two cups at a time, where a minute of cranking is not a chore
Who should skip it
- batch brewing for a household, where hand grinding becomes a daily chore
- anyone who wants to press a button and walk away
The thing worth knowing
A hand grinder usually out-grinds an electric one at the same price, because the money goes into the burrs rather than a motor. The trade is time: expect a minute or more for a single cup.

What we have not done
We have not independently tested this product. The description above is compiled from the manufacturer’s published specification and from what the category demands, and it is written to tell you who the equipment suits rather than to sell it. Where we have no first-hand experience, we say so rather than inventing a star rating.
