Query: Cheap, stopped working after a week

This product is CHEAP.bought the first one and it broke after a month. I thought it might have been my fault for leaving it on overnight. But the second one i bought only lasted 2 weeks!!!!So, buyers beware, if you are thinking about buying a long lasting replacement of your AC adaptor, DON'T BUY THIS ONE!
