The deciding figure is the published hopper capacity, which sets how many cups you can grind before a refill.

For quick weekday meal preparation, the grinder that removes the most steps is the one whose published hopper holds enough beans for several days and whose settings change with one dial. The CAUKINS lists a 120g hopper and 25 settings. The SHARDOR 64mm flat burr lists a 17.6oz hopper and 100 settings. The OXO Brew lists 12 ounces and 15 settings plus 43 micro-adjustments. The Hamilton Beach lists 16 ounces and 18 settings. The TIMEMORE C3S Pro is manual and lists 36 settings, with no hopper capacity published.
“Capacity and settings decide the weekday grind.”
Lush Editorial Team
Priorities, not a computed score. The inputs are published specifications, so we rank by what matters most and say how much.
The five picks differ most on published hopper capacity. The SHARDOR 64mm flat burr grinder lists 17.6oz, the Hamilton Beach lists 16 ounces, the OXO Brew lists 12 ounces and the CAUKINS lists 120g. The TIMEMORE C3S Pro does not publish a hopper capacity. A larger published hopper means fewer refills before a weekday grind, which is the step this page weighs most heavily.
Grind settings separate them next. The SHARDOR lists 100 programmable settings, the TIMEMORE lists 36 levels, the CAUKINS lists 25 and the Hamilton Beach lists 18. The OXO Brew lists 15 settings plus 43 micro-adjustments. The makers publish the counts, not the grind results, so the counts are what this page compares.
| Specification | CAUKINS | SHARDOR 64mm flat burr | OXO Brew | Hamilton Beach | TIMEMORE C3S Pro |
|---|---|---|---|---|---|
| Published hopper capacity | 120g | 17.6oz | 12 oz | 16 oz | not published |
| Grind settings | 25 | 100 | 15 plus 43 micro-adjustments | 18 | 36 levels |

The table does not tell you how long any grinder takes to grind a dose, how loud it is, or how evenly it grinds. None of the five makers publishes grind time in seconds or noise in decibels. The settings counts are published, but the grind each setting produces is not measured here. The table also leaves out the weight of the SHARDOR 64mm flat burr grinder, which the maker does not publish.
The SHARDOR 64mm flat burr grinder lists a 17.6oz hopper, the largest published capacity among the five. The Hamilton Beach lists 16 ounces and the OXO Brew lists 12 ounces. The CAUKINS lists 120g, which is about 4.2 ounces. A larger published hopper means fewer refills, which is the step this page weighs most heavily for a weekday routine.
The TIMEMORE C3S Pro does not publish a hopper capacity. Its maker states a 25g capacity in the product title, but the fact sheet does not list a hopper figure, so this page does not treat it as one. If capacity matters most, the SHARDOR and Hamilton Beach publish the largest figures.
The SHARDOR 64mm flat burr grinder lists 100 programmable settings, the most among the five. The TIMEMORE lists 36 levels, the CAUKINS lists 25 and the Hamilton Beach lists 18. The OXO Brew lists 15 settings plus 43 micro-adjustments. More settings can mean finer steps between brew methods, as the makers state, but the counts are not a measure of grind quality.
The CAUKINS states that its 25 settings cover espresso to French press. The Hamilton Beach states that its 18 settings cover extra-fine to coarse. The OXO Brew states that its 15 settings plus micro-adjustments cover espresso to cold brew. Each maker publishes a range, not a result.
The TIMEMORE C3S Pro lists 2.05 inches wide, 5.79 inches deep and 5.79 inches tall, the smallest published footprint of the five. The SHARDOR 64mm flat burr grinder lists 8.9 inches wide, 14.4 inches deep and 16.1 inches tall, the largest. The CAUKINS lists 3.9 inches wide and 7.5 inches tall.
Weight follows the same split. The TIMEMORE weighs 0.95 lb, the lightest of the five. The SHARDOR 64mm flat burr grinder does not publish a weight. The OXO Brew weighs 4.47 lb and the Hamilton Beach weighs 3.2 lb. A lighter grinder is easier to move, but the published weight says nothing about grind quality.
The TIMEMORE C3S Pro is manual and needs no outlet. The other four are electric. The SHARDOR 64mm flat burr grinder states 120V only and warns that 220V will damage it. The CAUKINS states a removable grinding chamber for cleaning. The Hamilton Beach states that its containers and lids are dishwasher safe.
The OXO Brew states a UV-blocking tint on its hopper. The SHARDOR 64mm flat burr grinder states an anti-static system and a stainless steel grounds container. The CAUKINS states a simplified maintenance routine with removable parts. None of the five publishes a cleaning time.
Large households. The SHARDOR 64mm flat burr grinder lists a 17.6oz hopper and 100 settings. It is the largest published capacity among the five, and its 8.9 inch width needs counter room.
Small kitchens. The CAUKINS lists 3.9 inches wide and 7.5 inches tall, with a 120g hopper and 25 settings. It fits a narrow strip of counter and still holds a published capacity.
Set-and-forget mornings. The OXO Brew states a one-touch start that remembers the last setting. It lists 12 ounces and 15 settings plus 43 micro-adjustments.
One grinder for coffee and spices. The Hamilton Beach states that its 18 settings suit herbs and spices too. It lists a 16 ounce hopper and a 2 to 14 cup selector.
Travel and no outlet. The TIMEMORE C3S Pro weighs 0.95 lb and folds its handle. It lists 36 grind levels and needs no cord.
Several figures a weekday buyer might want are not published by the makers.
The published figures that matter are hopper capacity and the number of grind settings. A larger hopper, such as the 120g listed for the CAUKINS or the 17.6oz listed for the SHARDOR, means fewer refills. More settings, such as the 100 listed for the SHARDOR, can mean finer steps between brew methods. Neither figure is a measurement of speed.
The SHARDOR 64mm flat burr grinder lists a 17.6oz hopper, the largest published capacity among the five. The Hamilton Beach lists 16 ounces, the OXO Brew lists 12 ounces and the CAUKINS lists 120g. The TIMEMORE C3S Pro does not publish a hopper capacity.
The TIMEMORE C3S Pro lists 2.05 inches wide, 5.79 inches deep and 5.79 inches tall, the smallest published footprint of the five. The SHARDOR 64mm flat burr grinder lists 8.9 inches wide, 14.4 inches deep and 16.1 inches tall, the largest. The CAUKINS lists 3.9 inches wide.
The OXO Brew Conical Burr grinder states a one-touch start that remembers the last setting. The Novalife lists a memory function, but it is not one of the five picks. The other four picks do not state a memory feature in their published features.
The Hamilton Beach states that its 18 precision grind settings are great for herbs and spices too. None of the other four picks states that it grinds anything beyond coffee beans. Check the maker's guidance before grinding spices in any grinder.
The TIMEMORE C3S Pro is a manual grinder with a foldable crank handle and no cord. It weighs 0.95 lb, the lightest of the five. The other four are electric and need a power source. The SHARDOR 64mm flat burr grinder states 120V only.
