Hario · Conical burrSmart G
A pocket-sized ceramic-burr hand grinder from Hario built for travel and pour-over, with an optional electric motor attachment for when your arm gives out.
The short version
This is a cheap, light, go-anywhere hand grinder for filter coffee, not a serious espresso tool.
Buy it for the price and portability, and accept that the small ceramic burrs and short handle mean it lags the current crop of steel-burr travel grinders on consistency and grind speed.
Why people buy it
- Very cheap entry point into burr grinding, well under most steel-burr rivals
- Genuinely compact and light, easy to toss in a bag for travel or camping
Why they don’t
- Small, relatively dull ceramic burrs mean more effort and less consistency than newer steel-burr grinders at a similar price
The full tally
- Very cheap entry point into burr grinding, well under most steel-burr rivals
- Genuinely compact and light, easy to toss in a bag for travel or camping
- Optional Electro Solo / Mobile Mill Stick motor attachment turns it into an electric grinder when you do not want to crank by hand
- Simple, intuitive to use with a clear hopper so you can see bean level and grind size
- Small, relatively dull ceramic burrs mean more effort and less consistency than newer steel-burr grinders at a similar price
- Short handle hurts leverage, so grinding a full hopper takes real arm work
- All-plastic body and small bearings feel and perform like a budget product next to the current wave of aluminum-bodied competitors

Years of owner threads, distilled — well regarded.
Solid value for filter coffee travelers at $75 CAD with simple maintenance and ceramic durability; ceramic burrs make espresso out of reach, and the upgrade treadmill (Comandante, Timemore Chestnut) is the expected path within 2-3 years—community recommends it as a temporary…

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Owners who grind daily or want espresso-capable consistency typically move up to a steel-burr hand grinder such as the Timemore Chestnut C-series or a Comandante C40, both of which offer sharper burrs, better bearings, and finer click adjustment for the same general travel-grinder niche.

Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new grinder gets blamed for it. These burrs pull syrup — naturals and classic medium roasts play straight into their character.

Common questions
Is the Hario Smart G good for espresso
Not really. It can grind fine enough in a pinch but the burrs are small and the adjustment is not precise enough for consistent espresso-grade grinding. It is built for pour-over, drip, and French press.
Can the Hario Smart G be motorized
Yes, Hario sells an Electro Solo (Mobile Mill Stick) motor attachment that clips onto the Smart G in place of the hand crank, turning it into a battery-powered electric grinder.
What is the difference between the Smart G and Smart G Pro
The Smart G Pro upgrades to stainless steel burrs and a sturdier, thicker-walled body with improved central rotation, while the original Smart G uses ceramic burrs in a thinner plastic housing.
