The ROCKURWOK publishes 7.48 by 8.66 inches and is the lightest at 1.68 pounds. The Chefman publishes 6.24 by 8.75 inches. The SUSTEAS Black publishes 7.16 by 7.16 inches. The Primula publishes 7.44 by 7.44 inches and stands 6.85 inches tall.

Frequently Asked Questions
Which of these takes the least counter space?+
By the published figures, the Cosori at 6.1 by 7.9 inches gives up the least width and depth of the five. The Chefman publishes 6.24 by 8.75 inches, the ROCKURWOK 7.48 by 8.66 inches, the SUSTEAS Black 7.16 by 7.16 inches and the Primula 7.44 by 7.44 inches. The WALDWERK publishes no dimensions, so it cannot be placed.
Does a smaller footprint mean a smaller capacity?+
Not here. The Cosori publishes a 1.8 quart size, the ROCKURWOK 1.6 quarts and the Primula 1.5 quarts. The two SUSTEAS kettles publish 2.6 quarts and the Chefman 1.9 quarts. The Cosori gives up the least counter of the five while publishing more capacity than the ROCKURWOK and the Primula.
Which kettle is the lightest to lift?+
The ROCKURWOK publishes 1.68 pounds, the lightest of the five. The Chefman publishes 2.3 pounds, the SUSTEAS Black 2.56 pounds and the Cosori 2.7 pounds, the heaviest of the five. The Primula, the GGC and the WALDWERK do not publish a weight, so no comparison can be made for those three.
Which ones whistle?+
The ROCKURWOK, the SUSTEAS Black, the Primula, the GGC and the WALDWERK all list a whistling spout in their published features. The Cosori and the Chefman are electric kettles and list auto shut-off instead of a whistle. The Cosori states it shuts off within 30 seconds of reaching a boil.
Which kettles list induction compatibility?+
The ROCKURWOK, the SUSTEAS Black and the GGC each state compatibility with induction, gas, electric, halogen and radiant cooktops in their published features. The WALDWERK lists induction, gas, ceramic and electric. The Primula is titled as a stovetop kettle and the Cosori and Chefman are electric, so neither is used on a burner.
What is not published for these kettles?+
Base diameter is not published for any of the five, and that is the figure that would settle whether a kettle sits well on a small burner. The Primula, the GGC and the WALDWERK publish no weight. The WALDWERK publishes no width, depth or height at all, so it cannot be ranked on counter space.

How the Five Compare on the Numbers
On a small counter the choice starts with two published numbers, width and depth. The Cosori publishes 6.1 by 7.9 inches, the least width and the least depth of the five. The Chefman publishes 6.24 by 8.75 inches, so it gives up 0.14 inches more width and 0.85 inches more depth than the Cosori. The SUSTEAS Black publishes 7.16 by 7.16 inches, the ROCKURWOK 7.48 by 8.66 inches and the Primula 7.44 by 7.44 inches.
Height and weight matter next. The Primula publishes 6.85 inches of height, the least of the five, which suits a shelf above the counter. The Cosori publishes 9.5 inches, the most of the five. On weight the ROCKURWOK publishes 1.68 pounds, the lightest, and the Cosori 2.7 pounds, the heaviest. The Primula does not publish a weight, so it cannot be placed on that measure.
| Specification | Cosori | ROCKURWOK | Chefman | SUSTEAS Black | Primula |
|---|---|---|---|---|---|
| Published width | 6.1 in | 7.48 in | 6.24 in | 7.16 in | 7.44 in |
| Published depth | 7.9 in | 8.66 in | 8.75 in | 7.16 in | 7.44 in |
| Published height | 9.5 in | 9.45 in | 9.45 in | 9.25 in | 6.85 in |
| Published weight | 2.7 lb | 1.68 lb | 2.3 lb | 2.56 lb | not published |
| Published capacity | 1.8 qt | 1.6 qt | 1.9 qt | 2.6 qt | 1.5 qt |
| Whistle listed | No | Yes | No | Yes | Yes |
| Auto shut-off listed | Yes | No | Yes | No | No |
| Induction listed | No | Yes | No | Yes | No |
| Handle stated cool to touch | Yes | Yes | No | Yes | Yes |
The table does not say how any of these kettles performs. Nobody at Lush has used them, and no figure here comes from measurement. Every number is what the maker publishes. Base diameter, cord length and boil time for a full kettle are not published for any of the five, so the table cannot settle whether a kettle sits well on a small burner or how long a full pot takes.
Counter Space, Read From the Published Figures
The two numbers that decide the fit
A kettle on a small counter competes with the cutting board, the coffee gear and whatever else lives there. Width and depth are the two published numbers that decide how much of that space is lost. The Cosori publishes 6.1 by 7.9 inches, the least of the five on both counts. The Chefman publishes 6.24 by 8.75 inches, which is close on width but 0.85 inches more depth.
The SUSTEAS Black publishes 7.16 by 7.16 inches, a square footprint that is 1.06 inches wider and 0.74 inches less deep than the Cosori. The Primula publishes 7.44 by 7.44 inches and the ROCKURWOK 7.48 by 8.66 inches. If the counter is narrow but deep, the Cosori and the Chefman are the two that give up the least width. If the counter is shallow, the Cosori and the SUSTEAS Black give up the least depth.
Height, weight and what sits above
Height only matters if something sits above the kettle. The Primula publishes 6.85 inches, the least of the five, so it clears a low shelf that the others would not. The Cosori publishes 9.5 inches, the most of the five, and the ROCKURWOK and Chefman both publish 9.45 inches. The SUSTEAS Black publishes 9.25 inches.
Weight matters when the kettle is lifted full. The ROCKURWOK publishes 1.68 pounds, the lightest of the five, and it is also the only pick under two pounds. The Chefman publishes 2.3 pounds, the SUSTEAS Black 2.56 pounds and the Cosori 2.7 pounds. The Primula does not publish a weight, so a reader who needs that figure has nothing to work from.
What Each Kettle Does Beyond Its Footprint
Materials and pour
The Cosori is the only pick whose maker states that no plastic touches the water. The Chefman states a borosilicate glass body with stainless steel accents and BPA free construction. The ROCKURWOK and the SUSTEAS Black both state Teflon and BPA free materials. These are claims from the makers, not results from use.
Pouring differs by mechanism. The SUSTEAS Black uses a push-button spout with a nylon and stainless steel handle. The Primula uses a flip-up whistling spout and a handle that folds down. The ROCKURWOK uses a wooden handle. The Cosori uses a precision spout and a cool-touch handle. The Chefman uses a 360 degree swivel base and a drip-free spout.
Heat sources and boil signals
The ROCKURWOK, the SUSTEAS Black and the GGC list compatibility with induction, gas, electric, halogen and radiant cooktops. The WALDWERK lists induction, gas, ceramic and electric. The Primula is titled as a stovetop kettle. The Cosori and the Chefman are electric kettles with their own bases, so they do not go on a burner at all.
Boil signals split the same way. The ROCKURWOK, the SUSTEAS Black, the Primula, the GGC and the WALDWERK list a whistle. The Cosori and the Chefman list auto shut-off instead. The Cosori states it shuts off within 30 seconds of reaching a boil, and the Chefman lists automatic shutoff and boil-dry protection.
Which One Fits Your Kitchen
Least counter to spare. The Cosori publishes 6.1 by 7.9 inches, the least width and depth of the five, and it is the only pick with no plastic in contact with the water. It stands 9.5 inches tall, so check the shelf above.
Lifting a full kettle matters. The ROCKURWOK publishes 1.68 pounds, the lightest of the five, with a wooden handle and a base listed for induction, gas, electric, halogen and radiant. It publishes 7.48 by 8.66 inches, so it asks more counter than the Cosori.
You want to see the water heat. The Chefman publishes a borosilicate glass body with blue LED lights that turn off at boil, on a cordless 360 degree base. It publishes 6.24 by 8.75 inches, so it is close to the Cosori on width but deeper.
You pour one-handed. The SUSTEAS Black uses a push-button spout and a nylon and steel handle, with a 2.6 quart capacity and a five-layer bottom. It publishes 7.16 by 7.16 inches, a square footprint.
You store it between uses. The Primula publishes a folding cool-touch handle and 6.85 inches of height, the least of the five, for a shelf or cabinet. It publishes 7.44 by 7.44 inches and a 1.5 quart capacity, the least of the five.
What We Could Not Verify
These are the figures and facts we looked for and could not find in the published listings.
- Base diameter for any of the five, which is what would settle a fit on a small burner.
- A published weight for the Primula, the GGC and the WALDWERK.
- Any published width, depth or height for the WALDWERK, so it cannot be ranked on counter space.
- Cord length for the Cosori and the Chefman.
- Boil time for a full kettle, as opposed to the smaller volumes some makers cite.
- Any statement of how these kettles perform, since nobody at Lush has used them.
