The jacks are very well constructed and seem to be very robust to withstand general gigging knocks and bumps. The cable itself is tough but I would recommend (as I would with any leads) to keep it wound properly to avoid it getting any kinks as it feels like it could twist and damage. Very good for the price though!
specs seemed good and I love those pancake ends, so I gave it a whirl....
BAM! This. thing. rocks. You will be amazed by this cable!!! Completely noiseless, very acceptable flexibility, extremely sturdy feeling plugs (well fastened), and a unique color to boot! This cable allows you to get heavy as you need with still having good articulation - no boosted frequencies here (that I could hear!).
I bought this and the 3m and the 3m is going back - strangely enough, this 6m has such a more full and clean sound, you would never know they were both the same cable.
