Buy the Cosori Electric Kettle.

It keeps plastic out of your water, boils faster, and owners actually like it more, and that is worth the extra cost.

What was compared

Cosori Electric Kettle, No Plastic Contact with Water, 1.7L, Black | Wide Opening, Easy to... — $53.77
OVENTE 1.7L Electric Tea Kettle, 1100W BPA-Free Water Boiler, Black KP72B | Fast Boiling, ... — $15.99

1. Your tea never touches plastic
Cosori's interior is borosilicate glass and stainless steel, so hot water only ever touches glass and metal. Ovente's body and lid are BPA-free plastic, meaning every cup still passes over plastic even if the resin is food-safe rated.
2. First cup lands minutes sooner
Cosori's 1500W element boils half a liter in under 3 minutes. Ovente's 1100W heater works harder for the same water, so every single boil throughout the day takes noticeably longer to finish.
3. You can actually scrub every corner
Cosori's dual-angle lid swings fully open for cleaning, letting you reach corners a narrow spout cannot. Ovente relies on a smaller opening and a removable filter, so mineral buildup is harder to reach and rinse away.
4. Owners are happier with it long term
Cosori sits at 4.5 stars across 49,000+ ratings, edging Ovente's 4.4 across nearly 60,000. A few reviews mention a rust spot on the heating element after months of use, but that is a minority complaint, not the pattern most owners report.
5. Yes it costs three times more. Buy it anyway.
Ovente is $15.99, Cosori is $53.77, a real gap on paper. But a kettle boils water you drink every day, and paying once to keep plastic off that water beats saving $38 up front. Unless plastic contact genuinely does not bother you, which plenty of budget buyers accept, the Cosori is the one worth owning.
