Our assessment
This is a manufacturer-document review, not a kettle test. Secura’s product page and instructions say no plastic touches the hot water: the pot, lid, spout and rim are stainless steel, and the fill marks are inside the kettle. The plastic sits on the outside, as a cool-touch shell.
Two gaps remain. Secura does not say what any lid seal is made of, and we found no test of this kettle for particle release. It suits the boil, settle and pour routine in our boiling-water guide. If the kettle you own works and isn’t plastic, keeping it is a sensible choice.
