OXO Brew Cordless Glass Kettle Review (2026)

Suits households that boil water mainly at a full boil for black tea, instant foods, and prep, and who value visibility and a tidy pour. Green tea drinkers who need 175 degree water should choose the Cuisinart PerfecTemp or a gooseneck model.

The borosilicate body with clear markings makes filling to the needed line exact, and you can watch the boil rather than listening for it. The insulated bottom is a thoughtful touch: the kettle can be set down with less worry about hot rings on counters.

The spout filter catches scale flakes, and owners praise a pour that starts and stops cleanly without the dribble common on budget glass kettles.

There are no presets, no keep warm, and no hold: fill, switch on, pour at a boil. At 1500 watts and 1.75 liters, it is quick for its size and simple enough for any guest to use.

Glass ownership means descaling to keep it clear in hard water areas and care when moving it around hard surfaces.

Against the Cuisinart PerfecTemp CPK-17, the OXO gives up six presets and keep warm for a clear view and simpler operation, at a similar capacity. Against the COSORI CGK-G173-KUS, the OXO feels better finished with its insulated bottom and filter, while the COSORI counters with an LED boil light, a stainless inner lid with no plastic water contact, and a budget tier.

Choose the OXO when visibility and pour quality top your list in a boil only kettle.

Glass ownership is mostly a visibility routine. Owners note scale shows quickly in hard water areas, which is useful warning rather than a fault: you can see buildup before it affects taste or speed. The spout filter catches scale flakes when pouring, and regular descaling with a vinegar or citric acid boil keeps the borosilicate clear, as the kettle guidance in this hub describes. The insulated bottom lets the kettle be set down with less worry about hot rings, but the glass body still needs more care than steel around hard surfaces. Owners who descale on schedule describe the pour and appearance staying clean over time.

Allow for the full weight in daily handling. The glass body weighs 3 lb empty and holds 1.75 liters, and owners say the kettle feels heavier when full than expected, so fill only what the next round actually needs.

The handle stays comfortable during that lift, and the cordless jug comes off its 360 degree swivel base, so a two-handed carry to the table is a sensible habit for a full boil rather than a one-handed swing.
