Is the Hario Mobile Mill Stick suitable for espresso grinding?
The Hario Mobile Mill Stick is primarily designed for coarser grinds suitable for filter coffee and French press. It is generally not recommended for fine espresso grinds (below 20 clicks or 40 Redclix on a Comandante grinder).
What grinders are compatible with this adapter?
The Hario Mobile Mill Stick is compatible with Comandante C40 MK3 and MK4 grinders, as well as Hario MSG-2T/TB and MSS-1B/TB series grinders.
How long does the battery last and how is it charged?
The Hario Mobile Mill Stick is USB rechargeable and can grind approximately 20g of coffee beans up to 25 times on a single charge, making it convenient for home, office, or travel.
Does the grinder ever jam or get stuck?
While the Hario Mobile Mill Stick significantly reduces the effort of manual grinding, some users have reported potential jamming issues if the bean chamber is completely full. It's best to add beans gradually or avoid overfilling for smoother operation.
