I've used these cables for around 8 years on pub gigs, school shows and outdoor events. They have been faultless. They coil nicely, have industry standard Neutrik connectors, meaning I can fix them without the connectors falling apart - not that they have needed repair at all. Excellent.
The only small down side is that the connectors are done up so tightly, you need a gripper or spanner to twist them apart should you need to get in to them for repair or to fit coloured boots. Apart from that, great!
