This is the only joint stereo cable around thomann, at least with male mini-jack and male jack ends. I've been using it to transform a left-and-right only output from a mixer into a joint stereo. It means you have the ability to have at least two separate outputs from the master L and R. It is very useful to me :)
The cable seems robust and quite durable, it isn't a PRO cable, but it makes what it says, and for the price that's actually good. The alternative for me would be to solder my own cables, and close to an event I don't have time for that.
Only thing to know, the rubber around it is sort of "rigid" (that's why the 4 stars) you know, you cannot really lay it down without having some curves, but with a bit of effort you manage to lay it down in the way you want.
