This snake cable (or multi-core) is great for many purposes, smaller setups, sub mixers, sub stageboxes etc., live or studio, at a bargain price. I use it when playing live without a sound tech. Then I have the mixer on the left side of the stage, the musicians who are close to it plugging in directly. I connect the M6 and put the box on the right side of the stage, so that the musicians standing farther away from the mixer can plug in without leaving the whole stage a total mess of cables.
The stagebox itself is quite solid, made of metal, good connectors which are numbered, thus making it easier to know what goes where (I use the corresponding numbers of the mixer channels). I usually play on smaller stages, so I would have liked the cable to be a bit shorter, but it is a good compromise length, it is still possible to use it with an off-stage mixer.
