Cosori Stainless 1.7L
$60 under your budget
No plastic touches the water — 304 stainless from spout to filter — and it adjusts in 5F steps from 105F to 212F, low enough for formula and warm drinks.

■ The catch — co-equal billing, always
Its specs are the maker's, not a lab's. None of the independent testers here has put this current stainless model on a bench — the plastic-free water path and the 105F floor come from Cosori's own listing. It also costs about $36 more than the glass kettle it replaces.

Traps — this verdict avoids
Why the Cosori Stainless 1.7L is right for you
It avoids every trap below — and for family of 4, under $150, it is the pick because it delivers:
"BPA-free" is not "no plastic"
BPA-free names which plastic is used, not whether any touches your water. Only 5 of the 11 kettles we compared keep every water-touching part in stainless — the rest put BPA-free plastic in the lid, the filter or the sight window.
Boil-only scalds green tea
A kettle without variable temperature goes to 212F and stops. Green and white leaf want 160-185F; boiling water strips them. If you drink anything beyond black tea or instant, temperature control is not a luxury.
A gooseneck is not your kitchen kettle
Pour-over goosenecks hold 0.8-0.9L against 1.7L for a standard kettle. Buy one as your only kettle and you boil twice to do what a standard kettle does once.
