I was immediately impressed with the quality of the packaging and the product itself. I bought purple and the color is really dramatic and beautiful. More importantly, I can tell that the cord is wrapped in a stiff fiber that is significantly stronger than the regular cotton fibers that wrap it. A real plug fits my devices snugly - they're the right size and not a tad flimsy like some. Have used that don't make a reliable connection (thus wobbling and getting damaged). I can't say for sure but I think they will last quite a while and be of great value. I will update my review if I find this not the case.
