To be honest I've only had this cable for 2 days. But based on several other NU cables I've used over the years, I think they're very good quality. This is the first one I've received with cargo attached; no problems so far. My favorites are the extension cord (great for home office and travel) and the leather strap that rolls up for a bag. I have one in every pocket. I love her. They also look sharp, better than regular white.
