Unfortunatley Chinese products will start to fail more and more. If you were not made aware of that thru various avenues then your head has been stuckin a place where foul smelling gases are stored and released. If you are an Electrical Contractor and know that the product was made in China, were warned about the inferiority of the product but installed it anyway you should be forever barred from ever working in the electrical industry. Yes, while I have lost numerous bids to the ( I just got my license and pedro is my helper working out of his garage and newely annointed contractor) I still have enough work to,and here's the most extremely important part, (sleep well at night) knowing I used quality components and devices and properly installed them. I truly believe that the small clause " same as or equal to" shoul be removed from any and all device take off sheets and building plans. Once again, corporate greed and the almighty profit margin win.
