Query: Weak power cord - damaged after little use.

I loved this at first, but soon became hazard. As others have stated, my power cord also developed exposed wires with occasional use. The notebook side of this power cord is very weak. I tried to extend it's life with electrical taping it up, but eventually that even failed with a spark and a trip of the circuit breaker. It was great while it lasted. Back to the OEM cord.
