Cosori Electric Kettle. No Plastic Contact With Water. Wide Mouth For Easy Cleaning. Auto Shut Off. 1.7L Tea Kettle & Hot Water Boiler. Water Heater & Teapot. Borosilicate Glass. Black. 1500W

I am returning this kettle because there is a silicone ring (EPDM rubber) gasket where the heating element/metal and glass parts join inside the kettle (highlighted in red in the photo). This may be food-grade material, but being next to the heating element, it will degrade over time and into the boiling water. Any time we have plastic or rubber exposed to light or heat, bad things will happen in the long run, such as deterioration of the material. It is best to buy a kettle that is solid glass or stainless steel, anything without plastic or rubber inside.

Nice kettle, works as described. However, in less than a week of use, I noticed a rust spot in bottom of the kettle (see photo attached). It bothers me every time I turn on the kettle. Cosori customer service was quite indifferent about my concern. He advised me to return it to Amazon for replacement or refund. It’s a pain in the neck to return a glass kettle when you have disposed the original packaging.

I love that this is all stainless steel and glass on the inside. I wish the sieve were removable without leaving plastic in contact with my steaming water.

The biggest problem with this is that it has an unstable base. It wobbles left to right when water is boiling, which to me is very unsafe. The bottom of the base that touches your countertop is a tripod. 3 little 1/2” circular feet extend just past the black plastic base. Why?? The black plastic base would be much more stable.

The cord is also extremely short. I have it plugged in under an island counter and the cord just reaches the top of the counter, making it more unsafe.

I wouldn’t buy this again.

Only had this for a short time but so far this kettle works fine and I like that the inner top is MOSTLY stainless. It's got some plastic that holds the strainer, so the boiling water still passes over some plastic but not nearly as much as other kettles. Heats water well and turns off no problem. My only real complaint is that it's very wobbly on the base. The base doesn't wobble, it's the kettle. The part where it connects to the base doesn't seem to fit very well, too much play. But I've decided to keep it anyway based on the stainless inner lid, wide top that makes it easy to pour water in and also access the inside for cleaning, good operation and ease of use. A friend has a Hamilton Beach of similar design and it doesn't wobble a bit on the base, but the whole inner top it plastic.

I have had this kettle for approximately six months. The water once it reaches the boiling point is now starting to smell like burnt plastic. Our instant coffee smells like burnt plastic why?? we thought the carafe was plastic, but after reading that it is made of glass, we are a bit confused as to why it smells

I paid a slightly higher price for this compared to other hot water kettles, specifically because they touted “no plastic” in their title and images. Personally I don’t think they should focus on this so much in their listing. I don’t mind if there’s plastic on the very top where not boiled water is not touching, but hot water definitely touches plastic with this product. You would have to keep the lid open while pouring if you don’t want the hot water touching the plastic part. I’ve had a bad experience with plastic melting in a hot water kettle in the past, so I really don’t want plastic in my kettle, especially where the water is going to touch. I’m returning this.

Other than this, it seems like it works totally fine. I tried it a couple times before I realized there was plastic (they suggested an initial boil before drinking the water so I didn’t think about it the first time).

I love the kettle, have had it since February and use it everyday. But I'm noticing some spots on the bottom, under the glass, that look like mold/tarnishing. I don't see it getting inside the water I'm using but it's not as pretty to look at anymore 😞 It does boil fast, and a sturdy piece. Myself and my kids love the beautiful blue light it shines while boiling, that's definitely the cherry on top.

After lots of Googling, cross-referencing different recommendations (and even getting some help from AI), we narrowed it down to two solid kettle options.

I compared price (not too cheap, but also not over $100), features, heating time, brand reputation, materials (I was only considering glass or stainless steel), and estimated lifespan.

We already own a Cosori air fryer - and aside from an annoyingly loud beep (which I muffled), it’s been a dependable workhorse for over 4 years. So I decided to stick with the same brand for the kettle.

This one has a cool blue LED ring around the base that lights up when it’s on - kind of like a blue gas flame. It’s a subtle but very nice touch!

Functionally, it’s almost there: sleek design, no distracting blinking lights, heats water quickly, and looks great on the counter. But there are a couple of design flaws that hold it back.

First, I really wish the glass container were double-walled — it gets very hot to the touch, which can be risky, and it doesn’t retain heat as well as it could.

Second, the lid has a built-in sifter contraption with moving parts that seems like it’s meant to filter or direct the pour. Unfortunately, it doesn’t actually work — it doesn’t seal the spout, and there are big gaps on either side (check the attached photos). So any filtering effect is purely cosmetic.

Those two downsides keep it from getting 5 stars from me. I mean, no need for sifter or moving mechanism - at all.

Yes, it makes some noise while heating - but honestly, that’s just part of the deal with kettles, electric or stovetop.

Boils water admirably, but doesn't shut off when water reaches a rolling boil. I let it go quite a long time, just to see, but no luck. Whether it shuts off when completely dry I can't say. Looking at the advertising copy above I see that they promise "Automatic shout-off", not "shut-off" so maybe I'll try hollering at it. Despite this I'll keep the kettle and not rely on its (faulty) safety features, since it looks nice, seems to work otherwise, and is easy to clean. Too bad about the non-working safety features though.

Is there possible lead exposure?

At the time of this review, the picture from the product box has a warning about possible lead exposure that I couldn’t find in the Amazon listing. It would be great if they specified if this was solely in the cord or if this is also on other parts of the kettle (ie in the glass or in the markings on the glass). Other similar products have notes online about the specific components, yet this product (and the website) only has this general warning that is the minimum legal requirement.

You’ll have to decide for yourself if this risk is worth it for a quick and simple boil time!

I had a slightly older Cosori model for 4-5 years before it stopped working, and got this one to replace it. I was surprised to find the cord no longer reaches the outlet from the kettle's usual location. They definitely cut corners and cheapened its product.
After the first use (following the water test in the instructions), the water tasted plasticky. Then I noticed the new model also has a bigger area of exposed plastic under the lid. See photos.
Way to cheat your customers, Cosori.

This is my second kettle after accidentally breaking the first one. My second kettle has died an unexpected death after 3 months. I know I drink a lot of tea but I would expect such an item to last much longer. The issue was that it suddenly wouldn't “connect” or stay on. After unplugging and reconnecting as well as ensuring all was clean, it did turn on and work but something didn’t sound right and so I am once again replacing. The main features that I love about this item are:
• temperature selection
• auto shut off
• price
• size

Photos are the bottom of the kettle, both interior and exterior as well as the base.

We've only had it a couple months so I can't speak to longevity. Its 7 c. max fill line is about 1/2 way- but you can see in my photo, boiling water doesn't bubble much over that at all. So why the extra glass? Just extra weight. It's ok using to lift it empty, but it's pretty heavy after adding only 4 c water, so I need to use both hands. To fill our 43 oz coffee press (shown on the left) doesn't it filled above 4-c on the Cosori. (and it is pretty heavy to me only filled that high) Unusable height above the fill line makes kettle too high to slip under an 8" water spigot like ours, (shown on the right). I do like that the strainer is built on the lid- it's out of the way when the lid opens with a button on the top of the handle. The Cosori replaced a stainless steel Hamilton Beach kettle we'd used for 15 years (shown far-R). The H.B. contact finally became intermittent, but it never rusted (new models seem to rust or corrode). I read reviews on so many competing kettles- it seems HB isn't making them like they used to. I decided on the Cosori even with a few complaints about water spots on the bottom heating plate- yes ours shows them already, but that doesn't matter to me. My complaint is weight/height. You'll probably need to use both hands to lift or position under a faucet. We have a dedicated water spigot at the sink for filtered water- very handy and the old kettle could slide under it without having to hold in a tilted position, or even lift, just slide over. I miss that.
