I once ordered a cheap chinese
generator from Amazon. It was pretty big - almost 3000watts. They were prohibited from taking it back because it contained fuel/oil.
It was broken of course. They gave me a refund and told me to throw it out or give it to someone. I gave it to a neighbor that likes to tinker with engines. I think he got it running.
I took the money and went to my local dealer and bought a Honda.
