This kit manages everything it should, no complaints there; these cables are essential to get the most out of the (in my opinion excellent) QuNexus itself.
However, the quality does not seem on par with the QuNexus, and that goes for build quality as well as visual design. The cables seem cheap next to my eurorack patch cables, it's as if they were sourced from China as an afterthought to the main device.
They are also much too long for my needs (the voltage controlled device sitting next to the keyboard itself), though obviously this is a subjective complaint and others will have different needs. The cable are also relatively thin, and they hold the shape they are twisted to. It's impossible to get them to straighten out, unlike standard eurorack patch cables. This quality, combined with the length, causes them to always form an inconsolable mess next to the QuNexus.
All in all, they do work, but I am going to replace them with sturdier, nicer looking alternatives worthy of the QuNexus.
