Does anybody knows if this box is working in Mairlist 7 ?
I want to use it to give 12 commandos.
Will the manufacturer post an image of the openend device? 
Given the “no drivers required“ information, I assume, on the inside one of the infamous Zero Delay Arcade USB Encoders is performing, which woud mean that it might be working with mAirList. In this case, what will most likely not work is a specific management of the individual LEDs (which is questionable to work anyway, rather rendering the LEDs lighting up altogether).
I do not know this device at all, but am drawing conclusions accounting to the sparse infoirmation given by the manufacturer. So don’t blame me on possible bad purchase.
