This part has failed after 5 months of very infrequent use. I saved this as a backup and it occasionally lived in the trunk of my car (maybe 12-15 times). Unfortunately it only expired yesterday. I suspect they won't last more than a few bends within the cheap wire and the metal core will snap. The metal core is likely made from an inferior metal like aluminum that doesn't have the flexibility of a copper braid. My original Lenovo charger is used daily at my workplace and is often moved from the office to other rooms. problems with it. You get what you pay for.
