How the Five Compare on the Numbers
The five grinders here share a conical burr design and a published range from espresso to French press, and they separate on counts and figures. Grind settings run from 45 on the AAOBOSI to 60 on the Breville, with the SHARDOR at 51 and both the AMZCHEF and the IAGREEA at 48. Timer increments run from 0.1 seconds on the SHARDOR to 0.5 seconds on the AMZCHEF.
Footprint is where the figures diverge most. The IAGREEA publishes 4.52 inches of width and the Breville publishes 8.46 inches, a difference of 3.94 inches. Heights sit closer together: 13.4 inches on the AMZCHEF against 15.33 inches on the Breville, a gap of 1.93 inches. Three of the five publish a weight and two publish none at all.
What the table cannot tell you is how any of these grinders performs, because nobody at Lush has used them and no maker publishes particle distribution, noise or extraction figures. What it does show is how much each one is willing to state. Breville publishes a voltage and a warranty that the other four leave blank, and withholds the burr diameter all four of them give.
Grind Settings and Timer Control
What the Setting Counts Say
The Breville publishes 60 grind settings, the highest count among these five. The SHARDOR publishes 51, the AMZCHEF and the IAGREEA each publish 48, and the AAOBOSI publishes 45. A higher count means more selectable positions between the finest and the coarsest end, which is room to adjust a shot without stepping past the point you wanted.
What none of the five states is how those steps are spaced. A grinder with 60 positions could put most of them in the drip range and leave espresso with a handful, and nothing in any of these listings rules that out. The count is a published figure and the spacing is not, so read the count as a ceiling rather than as resolution.
Timer Steps and Maximums
Three picks publish a timer increment. SHARDOR states 0.1 second steps up to 60 seconds, the finest step on this page. Breville states 0.2 second increments on what it calls a precision digital timer. AMZCHEF states 0.5 second accuracy with a 40 second maximum. IAGREEA and AAOBOSI both publish a 40 second maximum and no increment at all.
Cup counts are published three different ways. SHARDOR states one to twelve cups, AMZCHEF states two to twelve, and the Breville says its LCD shows the number of shots or cups selected without giving a range. AAOBOSI says the LED display selects a cup count, again with no range, and IAGREEA publishes a rotary knob for time rather than a cup count.
Hopper, Power and What Comes With It
What Each Hopper Holds
Three of the five publish a hopper capacity. Breville lists 18 ounces, the largest capacity on this page. AMZCHEF lists 10.6 ounces and adds a UV blocking tint and a trap door that closes when the hopper comes off. IAGREEA lists a 300 gram hopper, which is roughly 10.6 ounces. SHARDOR and AAOBOSI publish no capacity at all.
Capacity decides refills and nothing else. None of these makers publishes a figure for how long beans stay fresh in a hopper, so the UV tint on the AMZCHEF and the lid sealing cap Breville ships with its grounds container are design claims rather than measured ones. Two picks leave a buyer with no capacity figure to plan around.
Wattage, Voltage and the Warranty
Two picks publish a motor figure. Breville’s last bullet states 165 Watts and 110 to 120 Volts, and it is the only listing here that gives a voltage. IAGREEA states a 150 W high torque DC motor and a 450 RPM low speed design, the only RPM figure on this page. SHARDOR, AMZCHEF and AAOBOSI publish nothing about the motor.
Breville is also the only pick that publishes a warranty, two years limited, and the only one that lists what is in the box: two portafilter cradles, a grounds container with a lid sealing cap, a conical burr and a cleaning brush. IAGREEA states a portafilter holder for 51mm and 58mm baskets, and SHARDOR states a cradle without giving a size.
Footprint and Placement
Width, Depth and Height
Four of the five publish a width between 4.52 and 5.1 inches: IAGREEA 4.52, AAOBOSI 4.72, SHARDOR 4.9 and AMZCHEF 5.1. The Breville publishes 8.46 inches, which is 3.94 inches more than the IAGREEA figure. Depth runs the other way: the Breville publishes 6.28 inches while the AMZCHEF and SHARDOR both publish 7.4 inches.
Height matters under a cabinet. AMZCHEF publishes 13.4 inches, SHARDOR 13.5, IAGREEA 13.77, AAOBOSI 14.17 and Breville 15.33, which is 1.93 inches more than the AMZCHEF figure. A hopper has to come off the top of most of these, so clearance above the stated height is worth measuring too, and no maker publishes that.
Weight and Anti Static
Three of the five publish a weight. AMZCHEF publishes 5.4 pounds, the lightest published weight here. SHARDOR publishes 6.15 pounds. Breville publishes 6.39 pounds, the heaviest published weight here, a difference of 0.99 pounds from the AMZCHEF. IAGREEA and AAOBOSI publish no weight at all, which on a machine you lift to clean is a real gap.
Anti static is stated by four of the five. AMZCHEF names built in anti static technology and a stainless container, SHARDOR calls its ground coffee chamber mess free, IAGREEA claims reduced dust cling with a stainless outlet, and AAOBOSI names an anti static outlet. The Breville bullets never use the word, which does not mean the grinder lacks it, only that the maker does not claim it.
Which One Fits Your Kitchen
The cook who wants the most positions. Breville publishes 60 grind settings, 0.2 second timer increments, an 18 ounce hopper, 165 Watts and a two year warranty. It also publishes 8.46 inches of width, so measure the counter first.
The cook with a narrow gap beside the machine. IAGREEA publishes 4.52 inches of width, a 150 W motor at 450 RPM, 48 settings, a 300 gram hopper and a portafilter holder for 51mm and 58mm baskets. It publishes no weight.
The cook dialing in by the tenth of a second. SHARDOR publishes 0.1 second timer steps up to 60 seconds, 51 grind settings, one to twelve cups and 6.15 pounds. It publishes no hopper capacity at all.
The cook who moves the grinder. AMZCHEF publishes 5.4 pounds, the lightest published weight here, 13.4 inches of height, a 10.6 ounce hopper with a UV blocking tint, 48 settings and 0.5 second timer accuracy.
The cook who wants a middle option. AAOBOSI publishes 45 grind settings, a 40 second timer, an LED display and 4.72 inches of width. It publishes no weight, no hopper capacity and no motor figure.
What We Could Not Verify
Several figures that would matter for a buying decision are not published by these makers, and none of them were estimated.
- A burr diameter for the Breville, which names a conical burr among its accessories while the other four publish 40 mm.
- A hopper capacity for the SHARDOR and the AAOBOSI, neither of which states one.
- A published weight for the IAGREEA and the AAOBOSI.
- A motor wattage for the SHARDOR, the AMZCHEF and the AAOBOSI, and a voltage for any pick but the Breville.
- A noise figure in decibels from any of the five grinders.
- A warranty period from any pick but the Breville, which states two years limited.
