I ordered a few of these cables but have only opened one so far, and have only used it a couple of times.  Nevertheless I've used a lot of cables in my life and these have the look and feel of quality products.  The connectors are solid and well-molded.  They have good strain reliefs.  The cable jacket is thick enough that it should be able to stand up to regular use.  The cables are thick and comfortably pliable without being wimpy.  Unless there's some hidden weakness that I can't spot from the outside I fully expect these to last me for decades.
