I got one of these for free on a trashnothing Facebook group in my city. Someone was giving it away because it didn't heat anymore. I popped it open and replaced the thermal diode. I've had to do that twice now. Great kettle for all types of teas and pour over coffee, but they should really make them more robust if they're just expecting most people to toss it when a small inexpensive part goes bad.
Have a couple of these and the buttons are inconsistent. Can take multiple presses to turn on, apparently a common issue with no fix. I still like them since it’s a pretty minor fault, but worth knowing before buying
Moving parts and complexity makes it more prone to failure.
Also, how much energy do you need to keep this working? It's not said on the website.
Granted, both kettle and this zori trade energy and complexity/failure-potential for convenience. Much more so the zori. How much is unknown.
On the simple, less-energy end, you'd use an electrical resistance in an insulated jar.
All electric kettles will fail at some point. They have moving parts and are designed for obsolescence.
In my place I use a kettle that allows me to boil 1 cup of water. The filter mesh has failed long ago but the water does not have hardness. Instead I use a small improvised cap to keep the flow of vapour to the cut off thermostat (usually at the bottom of the handle).
These are pretty much the go-to style of "kettle" in Japan and similar alternatives are much cheaper over there if anyone is planning a visit - just note the voltage difference because you may need a transformer
That said, my stainless steel Tefal (T-Fal for those in north america and Japan) kettle has not failed me yet after 6 years of use, if/when it does fail i'll probably be considering one of these!
I recently got the OXO Gooseneck and it seems quite solid. Everything in contact with the water is steel, and you can dial the temperature which is quite nice for better tea and coffee.
Bare in mind that whatever you buy, stainless or plastic, the first thing to actually break if you take well care of it that is, is most likely the heat element itself. I don't know of any brand that sells kettles with replaceable heating element but would be nice. Second also remember ergonomics. Steel is heavy and can corrode while a simple sturdy plastic kettle is much lighter and won't corrode.
Hear me out: plain kettle on an induction stove. A far wider kettle selection plus your induction stove can be used to cook all sorts of things without poisoning you with CO.
That's what I did. Plus you can cook outside with it too. It's quite practical. My only complaint is that the fan makes some noise and I'm rather sensitive to white noise. Still much less noise than an exhaust fan (which I need to run on my gas range).
I've got a cheap black and decker one that I'd like to replace (eventually). It works fine, but I'd rather have something with a smaller physical footprint and better quality.
Mueller Ultra Kettle: Model No. M99S 1500W Electric Kettle with SpeedBoil Tech, 1.8 Liter Cordless with LED Light, Borosilicate Glass, Auto Shut-Off and Boil-Dry Protection
I've had 20€ kettles that work for years and and 20€ kettle that break once the warranty is over. Cheap electronics are a gamble. So is expensive ones, but I feel that with those you can at least try to find a trusted brand.
