There was a discussion on another group that discovered that 100% of these particular units from one particular run had the Hot and Neutral wires reversed by color. When repaired, 30% of them overheated. When returned, the company refused to refund stating that the repair (reversing the wires) voided the warranty. In a word, China.

You get what you pay for in electrical equipment. Shoddy/defective goods can kill. And sometimes do.
