My microwave is a 1977 Amanda Radarange. It can boil a cup of water in ⅕ of the time a modern microwave can.
Now granted, it has zero fancy settings and a simple number pad that does nothing but set how long you want the microwave to run.
But honestly, this simplicity is a large part of it’s charm. No connectivity needs, no features locked behind paywalls, no extraneous bullshit or never-used features. Just a tool that does only one thing, and does it exceptionally well.
I got a "retrowave" in mint green. It's dumb, uses a turn dial to set the cook time, stands on little feet like it's from Rocko's Modern Life, and looks like it's from the 50's. Have a matching toaster and eventually want a matching fridge.
It's been 4 years and no issues which is more than I can say about a lot of other new appliances we've gotten for the house.
For dumb appliances with a fun aesthetics look up 'retro (name of appliance here) and you'll get all the brands who make stuff like that. It's the only way I've been able to avoid smart garbage so far.
The fridge will likely operate far less efficiently than a modern fridge unless you have it rebuilt.
With that said, a rebuilt fridge - with a more efficient cooling system and better insulation and all seals redone, etc. - does not cost significantly more than a new midrange fridge.
Well, most of the fridge is already there. You just need to disassemble, sandblast the metal and paint (if the paint is in poor condition), replace the insulation with closed-cell spray foam, replace the refrigeration system with a modern Freon-free system, reassemble and put new seals on.
An old fridge can be quite simple, structurally speaking. It’s in the 70s and 80s when fridges started getting compact, difficult to repair, and disposable.
That's fine if you like the appearance of "retro" appliances, but that is certainly not the only way to avoid smart devices. Most microwaves, toasters, etc sold are not smart devices.
