COSORI Speed-Boil Electric Glass Tea Kettle

It's genuinely quick. Users consistently mention this is one of the fastest kettles they've used - we're talking noticeably faster than stovetop or other electric kettles. The 1500W heating element gets 1.7 liters to a rolling boil in just a few minutes. If you're making multiple cups of tea throughout the day or hate waiting around, this speed is a real standout feature.

It's both, honestly. The transparent glass with blue LED lighting is gorgeous and lets you see exactly how much water you're boiling, which is genuinely useful. The wide opening makes it super easy to clean compared to opaque kettles. That said, glass does mean more mineral buildup visibility and you need to be careful not to knock it around - a few users have experienced cracks or the handle detaching from the glass body over time.

No, this is a straightforward boil-only kettle. It heats water to a full boil and then automatically shuts off - there's no way to stop it at lower temperatures like 175°F for green tea or 200°F for oolong. If you're a tea enthusiast who wants precise temperature control, you'll need to boil and then wait for it to cool down, or look at a different model with variable temperature settings.

This seems to be hit or miss. Many people get a solid 2-3 years of daily use, which is decent for the price point. However, there are reports of issues like the handle breaking off, lid components failing, or the glass cracking. The durability isn't quite what you'd get from a premium stainless steel model, but if you treat it gently and descale it regularly, it should serve you well for a couple years.

The glass doesn't cause more buildup, but it definitely makes it more visible. Users mention pretty rapid scaling on the heating element at the bottom, especially if you have hard water. The good news is the wide opening and transparent body make it really easy to see when it needs cleaning and actually get in there with vinegar or descaling solution. Just plan on descaling it regularly - probably every few weeks if your water is hard.

Yes, the handle stays cool to the touch even during operation, which multiple users specifically appreciate. You can safely pour immediately after it boils without needing a towel or pot holder. Just be aware that while the handle itself is well-insulated, some users have reported the handle eventually detaching from the glass body after extended use, so it's worth checking that connection occasionally.
