Its most certainly made in china and I wouldn't run it at its rated capacity as I'm sure they rated it as high as they possibly can, this is no different to mile marker.
It may also be inefficient, either by pulling a whole lot more current that it should or by using a weaker motor and under gearing which will make it run slow. Either way you will not be able to winch as far or for as long as an identical power setup driving a Warn winch.
Don't use the cables that come with it. To drive a 10,000 pound winch with 20 feet of cable you are looking at big cable. Cable size is especially important if the motor is inefficient as it will be pulling more current.
On one hand you do get what you pay for, on the other that winch will more than likely save your butt.
You don't inherit the world from your parents, you borrow it from your children.
