This cable is great in every way. If you are looking for a short, thick gauge, flexible cable, this will suit you well. I have opened the connectors up to see how well the connections are made to each plug, from this I can confidently say that you should never really have any problems with it. The internals can easily be compared to a much more expensive "professional" standard, although this is in the lower price range.
The only constraint to this cable is that speakon connectors release mechanism is slightly more stiff than more expensive cables. However, I do believe that this a very minor issue as this is probably one of the cables that will see the least plugins and unplugs.
