I have one of these kits too. Bought it for the A4 CV outs.
They are very handy and I too find them very robust.
In fact I find them almost too robust.
The cables are a bit too thick and stiff for my liking. The coating is very heavy plastic. Something a bit more rubbery would have been nice. I like my cables to have a bit of flow and flex.
I wanted something far shorter, simpler and more flexible so in the end I just made my own. I only needed it for eurorack gear so didn’t need any of the bells and whistles of the Elektron kits. Seen some older thread on here where others had done similar custom cables that looked real nice so I bought a nicely made Neutrik insert cable and soldered my own mini jack plugs on the end. Mini jack are a ball ache to solder. For me anyways. But now I have a nice compact, short CV splitter cable. Well worth it. I’ll hang on to the Elektron one too. It definitely comes in handy too.
