I've been using these cables for more than 4 months and they are holding up pretty well.  For years I used seemingly indestructable guitar cables that were made for me by an electrician friend.  When they finally gave out, I got in the habit of using the no-name cables that are always on display near the register at Guitar Center- really more of an impulse buy than something I put any thought into.  After the third or fourth Guitar Center cable failed from light use I decided to try these cables.  Not only are they cheaper but they seem to be holding up better.  I am not terribly hard on my gear but my cables tend to get twisted as I move around and the cheaper ones  eventually fail mid-cable.  I don't mind spending a few extra dollars if the cable is a little more durable.  This cable is actually cheaper- $12 or so shipped- and it's holding up pretty well.  These are actually very reasonably priced for 18' cables.  There is some kind of limited life warantee on this product but I haven't needed it.  Five stars for a nicely made 18 foot guitar cable that costs $12 shipped!
