The Kettle You Can See Through, or the One You Can Set Down Fast?

Cosori's glass kettle and COMFEE's stainless steel kettle boil the same 1.7 litres. The daily difference is how you check the water, lift the lid and clean the vessel.

30-second verdict

Choose the Cosori glass kettle if seeing the whole water level, a wide cleaning opening and a glass body matter most. Choose the COMFEE stainless steel kettle if you prefer a metal vessel, a side water window and a push-button lid. Both checked 1500 W offers had automatic shutoff, boil-dry protection, Prime delivery eligibility and Amazon.com as seller and shipper. Neither selected model offers temperature presets.

The borosilicate glass body makes the fill level visible around the kettle. The wide mouth and large-angle lid are useful if you descale frequently. Its stainless steel inner lid and filter are part of the selected listing's no-plastic-contact design claim; inspect the actual item if that is your decisive criterion.

$24.28 checked 23 Sep 2026

The 304 stainless steel inner pot, side water window and push-button lid suit a straightforward boil-and-pour routine. The listing specifies a removable nylon filter, so this is not a plastic-free water path. Use the handle after boiling: the checked feedback notes a warm exterior.

What we researched

We used Amazon US's Best Sellers-sorted electric-kettle search to shortlist several brands, then opened the exact Cosori black glass and COMFEE stainless steel offers. Both were new, in stock, sold and shipped by Amazon.com, and showed a Prime member delivery option to the checked US address. Search cards showed 20K+ and 10K+ bought in the past month; the detail pages showed 30K+ and 9K+ respectively. We do not combine or reconcile these different snapshots as a single purchase count. They describe the selected listings at different surfaces or update times, not total US popularity. Rating totals may include variants; the individual review notes below concern the selected colour and size.

Key findings

Choose the vessel you want to use and clean daily

The glass Cosori makes the entire water level visible and its broad opening invites easy wiping. COMFEE gives you a steel pot and a push-button lid, but only a side window for the fill level.

High

Neither offer is a temperature-control kettle

Both selected listings describe straightforward 1500 W boiling with automatic shutoff. If you need preset temperatures for tea, these exact models are the wrong purchase even though the brands sell other variants.

The review details match the daily-use tradeoff

The checked Cosori feedback mentions quick boiling and easy descaling. The COMFEE feedback highlights the visible heating light and clean pour, with a reminder that the exterior warms after boiling.

Pre-purchase checklist

Confirm the exact ASIN, black glass or stainless steel option and 1.7 L capacity before ordering.
Recheck new-condition stock, Amazon.com seller, Prime eligibility and delivery to your address.
If you need adjustable water temperature, choose a different model rather than another colour of either kettle.
Handle the hot vessel by its grip and follow the model's descaling instructions.
