What to know about Cosori Electric Glass Kettle 1.7L (Blue LED; GK172/GK173 series)

This basic boil-only kettle has a borosilicate glass body and a stainless steel inner lid and filter. It is the cheapest widely sold kettle that its maker says has no plastic contact with water. Tom's Guide picked it as the budget option for buyers avoiding plastic. It suits anyone who wants to see the water and just boil it.
Editorial notes

Why it stands out

Why we like it

The listing states 'No Plastic Contact with Water', and the body is entirely glass. Tom's Guide picks it as its budget option for avoiding plastic. The filter is stainless steel, and it is sold by Amazon at a very low price.

It is the easiest way to start avoiding plastic in your kettle without spending much.

What to know

Skip it if you are strict about lids. A reviewer reports a plastic rim on the lid, and the Prop 65 lead warning does not name the part. Cosori sells several near-identical glass kettles, so confirm the listing mentions the stainless inner lid and filter.
