I'm an electronics designer and repair person. A client had bought a piece of equipment that wasn't working.
Client: I accidentally plugged it into 230V outlet instead of 24V and now it doesn't work... can you repair it?
Me: I could, but honestly it would be cheaper to buy a new one.
Client: Really? The casing looks fine.
Me: The casing is fine. Everything else is not.
He ordered a new one.
