The Adagio Teas UtiliTea Variable Temperature Electric Kettle is considerably more affordable than the Breville IQ Kettle but has a much smaller capacity. Still, it boasts lightning-fast heating capabilities and a strong, sturdy design. With a knob-style variable temperature adjustment for specific types of tea, it's a great choice for a one- or two-person household.
Heats up in minutes. The Adagio UtiliTea heats water to between 160 and 212 degrees Fahrenheit, ideal temperatures for delicate green teas to robust black teas, respectively. It also knocks heating performance out of the park: About.com guide Lindsey Goodwin says her kettle took just 1.5 minutes to reach 160 degrees Fahrenheit and about 3.5 minutes to get to a peak temperature of 212 degrees Fahrenheit. Its variable temperature dial is set to tea types rather than temperature markings, however, so you'll have to remember where the sweet spot is for your tea leaf of choice. While most Amazon.com users say they like the UtiliTea's sturdy stainless steel construction, some complain about its relatively small capacity of 1 liter.
Quick, efficient operation. The Adagio Teas UtiliTea Variable Temperature Electric Kettle has a clear strip to view the water, making it easy to tell how much is inside. Although its compact size may bother some heavy tea drinkers, cleaning it or filling it at a small sink is a breeze, notes TheKitchn.com. The kettle's removable base swivels 360 degrees and its pop-open lid makes it simple to operate one-handed. A cool-touch plastic handle is safe to grasp even at a full boil.
Plastic components may compromise safety. Like the Breville IQ Kettle, the Adagio UtiliTea contains plastic in its viewing window, which could lead to carcinogen exposure. This is a hotly debated issue among Breville IQ Kettle owners, but almost no UtiliTea users complain about it. A reviewer at ElectricCordlessTeaKettle.com reports that the lid gave off a plastic smell for the first few weeks, but others specifically say their kettles have no plastic odor. The UtiliTea appears to be quite safe overall, and Amazon.com users like its reliable automatic shut-off function.
While this informal write-up lists no specific methodology and doesn't compare the UtiliTea to other electric kettles, it helpfully reviews its key features from a consumer's perspective. Durand says she "can't recommend it highly enough" and calls it one of her "favorite appliances ever."
