We bought this cord to replace the dimmer that originally came with my wife's salt lamp. I installed this in a lamp and at the end of September it started flickering. I played around with it a bit but didn't tear it apart thinking I could get it back. Well, it's too late for that now. We unplugged it for fear it might burn down our house. I will spend my money immediately and buy a quality product from the hardware store and not waste my time again.
