Few months a go i was in China need to buy fridge for someone. The seller is connected to this big shot i know so don't dare to cheat me and he taught me how to choose.
These fridges, must see where it needs to exhaust the heat out, it's normally at the side or back.
You need to measure more than whether it can fit in.
If there's not enough allowance for the heat to release, your fridge made from where also won't matter because it won't defy the physics of overheating.
The difference between the better brand like Haier and the rest is the bottom is made of thick solid frame. I forgot why but he says it matters a lot.
I think you look at the weight vs the size first, if the weight is somehow off by a lot, that one most likely thin out in the material which has an effect on its longevity.
If the machine has an ice maker, avoid. Ice maker is the first thing to spoilt and it kills the whole fridge. This is what i learned from those USA appliance repair videos.
The surface got three types iirc.
One is laminate on, and can come off, those are the cheapest version.
Another one is the metal is somehow more lasting, i forgot the reason.
Last is glass which is the easiest to maintain but i think glass is heavier, so it may affect the weight and you need to factor that in the weight reading.
For my house, the bomb shelter door is right in front of where the fridge is and when fully open, the bomb shelter door will hit the fridge. This means that the glass option is out as it could easily shatter
