Among the best espresso grinders with touchscreens in this lineup, the Tuni G3 stands out for its 64mm flat burrs, 100 grind settings, and interchangeable hoppers; the SHARDOR CG018B offers unusually fine timer adjustments and a portafilter cradle; and the AAOBOSI CG223A suits a compact counter and straightforward timed grinding. Those differences matter more than the presence of a display alone: burr style, dose control, counter space, and how much flexibility you want shape the choice.

I ranked these models by how well their touchscreen controls serve espresso-focused home use, then weighed grind adjustment range, workflow, and practical compromises. The Tuni earns the lead for breadth and hardware, though missing size and weight details make its fit harder to judge. SHARDOR is a more defined choice for people who value precise timed dosing, while AAOBOSI trades some capacity and perceived material sturdiness for a smaller footprint. None is a universal pick: I’d match the grinder to your counter, brewing habits, and tolerance for setup adjustments.

Key Takeaways
Tuni G3 has the broadest adjustment range here, with 100 settings and 64mm flat burrs, but its dimensions and weight are not provided.
SHARDOR CG018B offers 51 settings and timer adjustments in 0.1-second increments, giving dose repeatability more emphasis than either rival.
AAOBOSI CG223A has the smallest stated footprint and a touchscreen for cup and time control, making it a practical fit for tighter counters.
All three include anti-static features, but that should be read as a mess-reduction aid rather than a promise of grounds-free cleanup.
Choose by workflow: Tuni for broad adjustment and hopper flexibility, SHARDOR for fine timer control and direct portafilter grinding, or AAOBOSI for compact placement.

More Details on Our Top Picks
Tuni G3 64mm Flat Burr Electric Coffee Grinder, Silver
The Tuni G3 is my best overall pick because it pairs the largest stated burrs in this group with the widest adjustment range: 64mm stainless steel flat burrs and 100 grind settings. That combination gives a buyer more room to tune settings across espresso and other brew styles than the 51-setting SHARDOR or 45-setting AAOBOSI. The number of steps alone does not prove finer espresso or better flavor, but it does offer more adjustment points for someone who likes to refine a recipe rather than settle quickly on a setting.
Its touchscreen supports single, double, and continuous grind modes, with time adjustments in 0.5-second increments. Compared with SHARDOR’s 0.1-second timer steps, the Tuni is less granular on the stated timer increment, but it has more named modes and a notably more flexible hopper setup. The included 250g hopper suits keeping a larger amount of beans ready, while the 50g option is useful for smaller batches or a single-dose style. That versatility makes the G3 the strongest all-rounder on paper, especially for a household that changes brewing methods.
The reservation is fit: the provided details list no dimensions or weight, so I can’t compare its counter footprint with AAOBOSI’s compact body or say how easily it can be moved. Its one-year warranty and lifetime tech support are also worth separating: support access is listed for the product, but it is not the same as a longer warranty. I’d choose Tuni for its range and workflow options, not because the available details settle every question about build or day-to-day shot quality.
Pros:- 64mm stainless steel flat burrs are the largest stated burr size in this comparison.
- 100 grind settings provide the broadest adjustment range among these three.
- Interchangeable 250g and 50g hoppers support different batch sizes and workflows.
- Touchscreen offers timed single, double, and continuous grind modes.
Cons:- Dimensions and grinder weight are not provided, making counter-fit planning difficult.
- Its 0.5-second timer increments are less fine than SHARDOR’s 0.1-second steps.
- The listed warranty is one year; lifetime tech support should not be mistaken for extended warranty coverage.
Best for: Home espresso drinkers who want broad grind adjustment, larger flat burrs, and the option to swap between bulk and small-batch bean hoppers.
Not ideal for: Buyers who need confirmed dimensions before purchasing, want the finest stated timer increments, or prefer a grinder with a clearly documented compact footprint.
- Burr type:64mm stainless steel flat burrs
- Grind settings:100
- Bean hoppers:250g and 50g
- Display:LED touchscreen
- Grind modes:Timed single, double, and continuous
- Time increments:0.5 seconds
- Portafilter compatibility:51–58mm
- Warranty and support:1-year warranty; lifetime tech support
Our verdict“I’d choose the Tuni G3 for the broadest stated grind and hopper flexibility, provided its unknown size is not a deal-breaker.”
SHARDOR Conical Burr Espresso Coffee Grinder with Precision Timer 2.0, Touchscreen Adjustable Burr Mill, 51 Settings, Anti-static, Stainless Steel
The SHARDOR CG018B makes the most sense for buyers who want a clearly specified timed-grinding routine. Its touchscreen timer adjusts in 0.1-second increments up to 60 seconds, a finer stated step than the Tuni G3’s 0.5-second increments. Once a dose time is established for a particular bean and grind setting, that level of adjustment gives the user more room to refine the amount dispensed by time. It is still a timed dose rather than a direct measurement of coffee weight, so bean density and grind changes can affect the result.
Its 40mm stainless steel conical burrs and 51 settings place it between the other two on adjustment count: more than AAOBOSI’s 45, fewer than Tuni’s 100. What distinguishes it in daily use is the portafilter cradle, which supports direct grinding into the portafilter instead of requiring a separate catch cup and transfer. The anti-static design is intended to reduce scattered grounds, and the listed residual cleaner and brush support routine cleanup. Compared with the AAOBOSI, SHARDOR offers finer timer steps; compared with the Tuni, it gives up the larger flat burrs, extra settings, and two-hopper option.
The tradeoff is a more involved setup for someone new to timed dosing. The product details specifically note that its timer can have a learning curve, and I would expect owners to spend time finding a repeatable setting rather than relying on the touchscreen to choose one for them. At 4.9 pounds, it is also the heaviest unit with a stated weight here, though its listed dimensions remain relatively narrow. I’d rank it ahead of AAOBOSI for its more precise timer and direct portafilter workflow, but behind Tuni for buyers seeking the widest overall capability.
Pros:- Timer adjusts in 0.1-second increments up to 60 seconds.
- Portafilter cradle supports direct grinding into the portafilter.
- 51 settings span espresso through French press brewing.
- Anti-static design and included cleaning tools support tidier upkeep.
Cons:- Timer setup may take practice, especially for new users.
- 40mm conical burrs and 51 settings offer less stated range than the Tuni G3.
- At 4.9 pounds, it is heavier than a buyer seeking a highly portable grinder may prefer.
Best for: Espresso drinkers who want fine timer adjustments, a direct portafilter workflow, and a stated 51-setting range.
Not ideal for: Beginners who want a very simple setup, buyers who prefer a scale-based dosing workflow, or anyone seeking the broadest adjustment range and interchangeable hoppers.
- Burr type:40mm stainless steel conical burrs
- Grind settings:51
- Timer:Up to 60 seconds, adjustable in 0.1-second increments
- Capacity:1.4 ounces
- Dimensions:7.4 x 4.9 x 13.5 inches
- Weight:4.9 pounds
- Power:165 watts, 120 volts
- Material:Stainless steel
Our verdict“I’d pick the SHARDOR when fine timed dosing and direct portafilter grinding matter more than maximum grind range.”
AAOBOSI Espresso Coffee Grinder with Conical Burr, 45 Grind Settings, Anti-Static, and LED Touch Screen
The AAOBOSI CG223A earns its place for countertop practicality. Its stated dimensions—7.28 inches long by 4.72 inches wide—make it the smallest-footprint option among the grinders here with dimensions supplied. At 14.17 inches tall, it still needs vertical clearance, but the narrow base makes it a sensible candidate for an apartment kitchen or an office coffee station. Compared with the SHARDOR, its base is slightly smaller by the listed measurements, while its touchscreen keeps dose control accessible through cup and time settings.
Its 45 grind settings cover espresso through French press according to the product details. That gives it a useful range, but fewer adjustment points than either SHARDOR or Tuni. I’d view it as the straightforward space-saving alternative, not the pick for someone chasing the largest range or most refined timer increments. The stainless steel conical burr and anti-static outlet are practical features, while a portafilter holder compatible with 51mm and 53mm baskets supports direct use with common smaller portafilter sizes. Tuni lists compatibility across 51–58mm, so buyers with a larger portafilter should check that difference before deciding.
The main compromise is its limited capacity, which may mean more frequent refills in a household making several drinks. The product information also flags plastic construction, which may feel less substantial than a buyer expects from a metal-bodied appliance. I’d put AAOBOSI behind SHARDOR because it has fewer grind settings and does not list the same 0.1-second timer granularity, but its compact footprint can outweigh those differences for a cramped counter. It is the most sensible pick here when placement matters more than maximum adjustment flexibility.
Pros:- Smallest stated countertop footprint of the three grinders with dimensions listed.
- 45 grind settings cover several brewing styles, from espresso to French press.
- LED touchscreen provides cup and time control.
- Anti-static outlet and a 51mm/53mm portafilter holder support a tidier direct-grinding routine.
Cons:- Limited capacity may require frequent refilling for multiple daily drinks.
- Plastic construction may feel less substantial than metal-bodied alternatives.
- Its 45 settings provide less stated adjustment range than SHARDOR and Tuni.
Best for: Apartment dwellers, office users, or espresso drinkers who need a narrow countertop footprint and touchscreen cup and time control.
Not ideal for: Large households that grind often, buyers seeking the most durable-feeling construction, or users who need portafilter compatibility beyond 51mm and 53mm.
- Burr type:Stainless steel conical burr
- Grind settings:45
- Display:LED touchscreen
- Controls:Cup and time control
- Dimensions:7.28 x 4.72 x 14.17 inches
- Power:200 watts, 120 volts
- Portafilter holder:51mm and 53mm
- Features:Anti-static outlet and timer
Our verdict“I’d choose AAOBOSI when counter space is tight and a smaller footprint matters more than extra settings or larger capacity.”
How We Picked
I compared these three grinders against the specific promise of a touchscreen espresso grinder, rather than treating a display as a bonus that automatically makes a model better. I looked at how each interface supports everyday dosing, how much control the grind range appears to offer, and whether the listed hardware and form factor fit a home espresso setup. A touch panel is useful when it makes a repeatable routine easier; it is less persuasive if the details leave basic questions about capacity or countertop fit unanswered.
My ranking gives the Tuni G3 the top spot because its combination of 64mm flat burrs, 100 settings, multiple timed modes, and two interchangeable hoppers gives it the most expansive stated workflow. It does not win on every practical point: the missing dimensions and weight are real unknowns. I put SHARDOR next because its 0.1-second timer increments and portafilter cradle make its dosing workflow unusually specific. AAOBOSI takes the compact-counter role, with a smaller stated footprint and useful cup and time controls, while its limited capacity and plastic construction concern keep it behind the other two for buyers prioritizing heft or batch size.
I used the supplied product details only and did not infer unlisted performance, noise, durability, or espresso results. Where specifications are absent, I call that out rather than filling the gap with assumptions. The rankings reflect the stated features and tradeoffs, not a claim that any grinder will produce better shots for every bean, machine, or recipe.
Factors to Consider When Choosing Best Espresso Grinders With Touchscreens
I’d choose among these grinders by treating the touchscreen as one part of the workflow, not the deciding feature on its own. The useful questions are how you set a dose, how much grind adjustment you want, whether the unit fits your counter, and how often you need to refill it.
Decide what the touchscreen needs to do
Touchscreens in this group control different parts of the routine. SHARDOR emphasizes timer precision, with adjustments in 0.1-second steps. Tuni separates timed single, double, and continuous grinding into named modes, using 0.5-second increments. AAOBOSI provides cup and time control. If you already weigh doses, a timer may mainly help repeat a familiar workflow; it does not replace weighing the grounds. If you want a timed routine, compare the controls and increments rather than assuming all touchscreen interfaces work alike.
I’d also think about how many people use the grinder. A timed setting that suits one bean and dose can require adjustment when beans change, and touch controls do not eliminate the need to dial in espresso. Buyers who like making small changes may appreciate SHARDOR’s fine time steps or Tuni’s larger setting range. Someone who wants basic controls and a compact unit may find AAOBOSI’s approach adequate without paying attention to every adjustment option.
Read grind-setting counts with restraint
The listed ranges run from 45 settings on AAOBOSI to 51 on SHARDOR and 100 on Tuni. More settings mean more listed adjustment points, which can be useful when searching for a workable espresso grind or switching between brew methods. They do not, by themselves, establish how evenly a grinder cuts beans, whether every step is useful, or how easily it will produce a particular shot. Burr geometry, calibration, coffee freshness, and the espresso machine also affect the outcome.
For a buyer who mainly makes espresso, a long setting list can be less valuable than a control that is easy to adjust in small, predictable steps. The Tuni has the broadest stated range, while SHARDOR’s smaller count is paired with fine timer adjustments. AAOBOSI’s 45 positions may suit a user who wants flexibility across brew methods but values compact placement more than the highest number of settings.
Match burr design to your priorities
Two models here use conical burrs: SHARDOR lists 40mm stainless steel conical burrs, and AAOBOSI lists stainless steel conical burrs without a stated size. Tuni instead uses 64mm stainless steel flat burrs. Burr type and size can influence grinder design and the way a buyer compares equipment, but the supplied specifications do not support a promise about cup flavor or shot quality. I would use these details to distinguish the hardware, then look for reliable information about adjustment and workflow rather than predicting taste from burr shape alone.
If you want the most clearly specified burr size in this roundup, Tuni is the only model with a 64mm flat-burr specification. If you prefer a conical-burr option, SHARDOR gives a specific 40mm measurement, while AAOBOSI may be appealing when its footprint is the greater concern. None of these listings supplies enough information to rank burr alignment, retention, or particle distribution, so I would not treat those points as settled.
Check counter space, clearance, and capacity
AAOBOSI has the smallest listed base at 7.28 by 4.72 inches, though its 14.17-inch height still calls for clearance below cabinets. SHARDOR measures 7.4 by 4.9 by 13.5 inches and weighs 4.9 pounds, giving buyers a clearer sense of its placement and movement. Tuni’s product details omit dimensions and weight, which is a genuine planning gap if your counter is crowded. I would measure the available height as well as the base area before buying any of these tall, upright grinders.
Capacity changes the rhythm of use. SHARDOR lists a 1.4-ounce capacity, while Tuni includes 250g and 50g hoppers for larger or smaller batches. AAOBOSI’s capacity is not quantified in the provided details, but its listed limitation is that it may need frequent refilling for larger households. If several people make espresso in a row, hopper size and refill frequency may matter more than a few extra grind settings.
Consider portafilter fit and cleanup
A direct-grinding setup can reduce steps, but portafilter compatibility needs to match your basket. SHARDOR includes a portafilter cradle; AAOBOSI lists a holder for 51mm and 53mm portafilters; Tuni states compatibility from 51mm through 58mm. If your machine uses a 58mm portafilter, Tuni has the broadest stated fit in this group. If you use a smaller basket, the other two may suit your setup, but check the exact holder arrangement and how it positions the portafilter before relying on it.
All three advertise an anti-static feature or system. That can help limit scattered grounds, but it should not be interpreted as a guarantee that no grounds will cling or spill. SHARDOR lists a brush and residual cleaner for maintenance; the other descriptions emphasize anti-static design without the same cleaning-tool details. I would still plan for routine brushing and occasional cleanup, especially when changing beans or grind settings.
Choose the right compromise
My overall choice is Tuni G3 for a buyer who values 100 settings, flat burrs, named timed modes, and two hopper sizes, and who can verify the unit will fit. I’d choose SHARDOR for fine timer adjustments and a direct portafilter workflow, accepting a smaller stated capacity and a setup learning curve. AAOBOSI is the practical compact pick when its smaller footprint matters more than extra adjustment points, larger capacity, or a metal-feeling body.
Before choosing, identify the compromise you will notice every day. A little more counter width may be easy to accommodate; a hopper that needs frequent refilling may be less convenient in a busy household. Likewise, a broad adjustment range is useful only if you intend to use it. Matching the grinder to your routine is a better basis for choosing than buying the model with the longest feature list.
Frequently Asked Questions
Which touchscreen espresso grinder in this lineup has the most grind settings?
The Tuni G3 lists 100 grind settings, compared with 51 on the SHARDOR and 45 on the AAOBOSI. That gives it the broadest stated adjustment range, but the count alone does not prove better espresso results. I’d treat it as an advantage for buyers who want more points to explore, not a guarantee of a better shot.
Which model has the finest stated timer adjustments?
The SHARDOR CG018B has the finest stated timer steps, adjusting in 0.1-second increments up to 60 seconds. Tuni lists 0.5-second increments, while AAOBOSI lists cup and time controls without a specific increment in the supplied details. Fine timer steps can help refine a timed dose, though timed grinding does not directly measure the weight of the coffee.
Which grinder is the best choice for a small kitchen?
The AAOBOSI CG223A has the smallest stated base dimensions of the models with measurements provided, at 7.28 by 4.72 inches. Its 14.17-inch height still needs overhead clearance, so I’d measure under-cabinet space before choosing it. Tuni’s dimensions are not supplied, which makes it harder to recommend when fit is the main concern.
Do these grinders work with different portafilter sizes?
The product details list different compatibility ranges. AAOBOSI names 51mm and 53mm portafilters, while Tuni lists a range from 51mm to 58mm; SHARDOR includes a portafilter cradle but does not specify a size range in the supplied information. I’d confirm your machine’s basket diameter and the holder’s fit before buying, particularly if you use a 58mm portafilter.
Are anti-static features enough to keep the grinder clean?
All three listings describe an anti-static feature intended to reduce scattered grounds, but none promises a completely mess-free grinder. SHARDOR also lists a cleaning brush and residual cleaner, while the other product details do not give the same cleaning-tool information. I’d treat anti-static technology as a way to help limit mess, not as a substitute for routine brushing and cleanup.
Conclusion
I’d choose the Tuni G3 if I wanted the broadest stated adjustment range, 64mm flat burrs, and the option to switch between larger and smaller bean batches, provided I could confirm its dimensions before setting aside counter space. For a more defined timed-dosing workflow, I’d choose the SHARDOR CG018B: its 0.1-second timer steps and portafilter cradle give it a clear role, though the setup may take practice. If I were fitting a grinder into a smaller kitchen or office, I’d start with the AAOBOSI CG223A and accept its lower setting count and limited capacity in exchange for its smaller stated footprint. The right pick is the one whose controls, size, and refill routine suit how you actually make coffee.
