Our Verdict

If you want a gooseneck kettle, but the cost made you balk, then this kettle is for you. It's not as balanced as some of the higher-end models, and as a result, it doesn't pour as smoothly. It also lacks continuous temperature settings. So, if you're dialed in on your tea or coffee temperatures it will leave a lot to be desired. However, if you're trying out refined steeping and extracting techniques, this economic gooseneck will be a good fit.

Our Analysis and Test Results

Above all, the thing that makes this model notable is that it's a gooseneck kettle that won't break the bank. It's decent quality, it has some nice features like temperature hold, and temperature presets, and of course a gooseneck spout and articulated handle for slow pours. While the Cosori CO108-NK checks most of the boxes for high-end brewing, it lacks continuous temperature selections, and it is slow to reach a boil.

Boil Time

We tested boil time by pouring 4 cups of 57° F water into the kettle and suspending a digital thermometer in the water and closing the lid. Next, we initiate the boil and simultaneously start the timer. The Cosori reached a rolling boil at 4 minutes, 58 seconds. Not exactly a record time, but not too bad either.


Our pouring test is actually a measure of how well the kettle brews a proper pour-over cup of coffee. The process requires precise timing and that timing depends on being able to consistently control the flow of water discharged from the kettle into the grounds. Having a gooseneck and an angled handle give this model a distinct advantage in this test. However, in comparison to other gooseneck models, it's a bit rough and requires a bit more attention paid to the task for satisfactory results. Nonetheless, it is way better than a pitcher-style machine.

Given the combination of low-cost and specialty features, we find this kettle to be a solid value. However, this assessment comes with the caveat that if you end up going all-in on specialty tea and coffee you'll eventually want to upgrade to a machine with continuous temperature settings.

The Cosori CO108-NK is not a high-end kettle. However, it shares several features with high-end kettles but with the notable exception of price. This model has a decent pouring system for drip coffee, and a variety of temperature presets for different teas and coffee varieties. All in all, it's a stylish water heater that is competitively priced.
