I have many of these. They just don?t fail!
We have been using Cordial cables for a while, also Thomann ones, but I particularly have one of this for 2 years (and it was from my old band, so I have no idea how much it was used before), and it's been tru over 200 concerts as my guitar cable, and still going.
I would personally prefer cables to be 10 M long, instead, but 9 also works fine, and it is a really high quality and specially super good price / performance ratio.
PROs
over 200 concerts
nice lenght
durable and good connectors
Cons
could have been 10 m instead, but it is definitely not a problem at all.
In general I think Cordial cables work quite fine for the price, and I have seen many many colleagues working with them mainly.
