What to know about Cosori CEK-S153-VUS

Cosori's 1.7L all-metal-interior kettle with 5 presets, ±5°F adjustable temperature from 105–212°F, and a 60-minute keep-warm. Cosori says no plastic parts touch the water. It is the lower-cost way to get variable temperature in a plastic-free water path.
Editorial notes

Why it stands out

Why we like it

The Amazon title states 'No Plastic Contact with Water', and Cosori describes an all-metal 304 stainless interior. That is a clear maker claim in a kettle with real features: five presets, ±5°F adjustment and a long keep-warm window. At 1.7L it is far more practical for a household than the gooseneck options.

It is sold by Amazon and in stock, and it costs well below the premium variable-temperature kettles.

What to know

Skip it if you need independent test results. It is a newer model that no outlet has tested yet, and Cosori does not say what the lid seal is made of. Its page also carries a Prop 65 lead warning that does not name the part.
