The post I mentioned above was also PV related, fake Fotek failure though.
There are some items, I would not buy from Amzn/Ae like some Tuya smart relays from unknown manufacturers (with fake certificates) and solid state relays/switches especially if they are encapsulated, non inspectable.
I know I'm silly, because even bad USB-charger could start a fire in my house... It's kind of easier to accept and deal with low quality items than fake items.
