COSORI Electric Kettle Review
Pros: Great pitch-style spout, aesthetic design, cool LED lights
Cons: Poorly balanced, fragile, single temperature setting
Our Analysis and Test Results
The COSORI Electric Kettle is an all-glass kettle that sports some flair provided by the blue LED lights circling the base of the reservoir. More practically, it's the best pouring machine out of the pitcher-style models. The only knocks against it are its single temperature setting, the lack of temperature holding, and the limited insulation offered by the transparent reservoir. An additional concern is the fragility of the construction material.
The boil test we employ for our kettle reviews is simple and effective. We draw 4 cups of 57° F water and dump it into the unit. We then turn on the kettle at the same time as a stopwatch and wait for the water to reach a rolling boil. To add precision to the boiling point, we include a thermometer. At our lab's elevation, a rolling boil occurs at ~202° F. Clocking in at 4 min, 23 sec, the COSORI's boil time is about average for the class.
How a kettle discharges water from its spout is a critical aspect of its performance — particularly if you're shopping with pour-over coffee in mind. What we are looking for in this assessment is a spout that can issue a slow, even stream of water. In general, the pitcher-style kettles do not excel at this task. However, the rolled glass lip of the COSORI's spout makes this model a standout for precision among the pitcher kettles. Unlike the gooseneck models that are the best at slow pours, the COSORI can pour rapidly as well.
Ease of Use Features
The COSORI is a simple kettle that offers few ease of use features. However, the glass is marked with volume indicators in increments of 0.25 liters starting at 0.5 liters. Additionally, it has an automatic shut-off when the water reaches a boil and the lid of the unit is attached.
At GearLab, we define value in two ways. A product either shares the same features and quality as other products in its class while costing less, or it costs about the same amount of money but offers the consumer more features and better quality. By this definition, we consider the COSORI to be an exceptional value. The model is simple, good-looking, and modestly priced.
If you're looking for an attractive, effective, and affordable general-purpose kettle, then the COSORI Electric Kettle is a great option. This machine boils water relatively fast, the container has a large capacity, and it has a visually appealing light display to boot. If you don't have specialty functions — such as temperature settings — as a priority, then you can't do much better than this novel kettle.
