About COSORI
COSORI is a kitchen-appliance brand launched in 2016 by VeSync, a smart-home technology company headquartered in Shenzhen with US operations based in Anaheim, California. The brand built its name on its original WiFi-enabled air fryer and has since expanded into electric kettles, food dehydrators, pressure cookers, toaster ovens, and kitchen scales, selling millions of units across its lineup.
COSORI's air fryer line has drawn independent testing from outlets including Consumer Reports and Forbes Vetted, and TODAY named a COSORI model best overall in its own air fryer testing. In our own review of the electric kettle line, what stood out was the consistent focus on water-contact material safety: borosilicate glass and stainless steel bodies with no plastic in the water path, backed by an unusually large base of verified Amazon customer reviews.

COSORI Electric Kettle, 1.7L Borosilicate Glass
Zero plastic touches the water at any point in the boil cycle, since the entire body is borosilicate glass, and the wide-mouth lid lets you reach in and wipe out scale without a brush. It boils a full 1.7 liters in under three minutes on a 1500W element, and it carries the largest verified Amazon review count of any kettle in our testing at over 47,000 reviews and a 4.5-star average.

COSORI Electric Gooseneck Kettle, 5 Temperature Presets, 0.8L
The precision gooseneck spout delivers the slow, controlled pour that pour-over coffee needs, and the 1-hour HOLD TEMP function keeps water at the target temperature through multiple sequential pours without a manual reheat. In our testing it was the best-validated gooseneck kettle in its segment, with 19,000+ reviews and a 4.6-star average and an all-stainless interior that keeps plastic away from the water even during extended hold.
