Cafe (spinoff from GE) does a pretty good job with stoves. AFAIK they are still pretty well respected.

The brands to stay away from at all costs are LG and Samsung.

I do not - I've heard it so many times from so many places that I didn't bother checking it before repeating it, but it looks like it was wrong.

Someone already pointed that out, so I edited the post with strikethrough hours before you replied.

the hot happens in the pot and not inside the stove

The pot is sitting on the stove. And induction involves electromagnetism, which means it involves metal pots and pans, and metal loops of wire to induce current in that cookware. Metal parts conduct heat very well. So, induction stoves don't get quite as hot as conventional stoves. But, they still get very hot because they have a hot metal pot sitting on them.

Also, while induction stoves don't get quite as hot as other kinds of stoves, they involve large currents and large amounts of magnetism. That means both stress on the electrical parts, and mechanical stress from the magnets.

Overall, I'd guess that an induction stove is probably going to have fewer things that can go wrong with it than a gas stove, a glass-top stove or an olde fashioned electrical resistance stove. But, it isn't like an LED light or something that should last decades because there's no moving parts, no heat, no big currents, etc.

High end ones do too if you want to access all of the wash features; they can’t be entirely programmed from the device itself.

Man, having worked in a couple research labs in a previous life, there's no way I'd use a used lab scale for food. Especially when $50 will actually get you a pretty decent scale that has not been potentially used for weighing everything from diseased mice to stool samples to unidentified precipitates from a failed chemical reaction.

Since you're here to type this, it was probably not used for anything too nasty, but I do not endorse that as a way to save a few bucks!

One thing to note is that planned obsolescence for machines is not something that is easy to do to the level that you're describing it.

Even if they use substandard materials at specific junctures with an estimated wearout time limit, there's always the chance that a manufacturing flaw can increase the time between breakdowns

I think a good follow-up plan would be something more like finding the parts that break down and then digitizing them and then contracting with a service like JLCPCB to manufacture those individual parts on demand.

You could probably start a fairly successful company on just that if you had the time and energy to get the whole process rolling.

A combination of a SLS 3D printer to make the parts out of metal, or, you know, really high-quality 3D printer to make them out of nylon or whatever plastic is necessary, and getting the appropriate springs and levers and bearings and everything to fill in the gaps, you probably could make a nice side business for yourself just custom making the parts that break down the most often for appliances.

The water heater that came with my house I bought in '98 lasted 20 years.

And by the time you got rid of it it was criminally inefficient.

Replace your sacrificial anode before that time and you'll be good.

No warranty? If you bought with a credit card they usually have a warranty extension feature and will extend the manufacturer's warranty for you.
