Stairville DDC-6 DMX Controller

This was something I bought at a busy time and left it for months before actually sitting down with it. Unfortunately, it never worked and I never figured out why. I got my DMX led light working on its own, but I could never get this to control it (or really do anything). It was far too late to return it by then so I just left it. I don't know for sure that it's faulty but I did enough reading about how it was supposed to work that it's the only conclusion I've been able to reach.

cheap and cheerful but not stunning - DMX resolution is a bit steppy but for a cheap manual desk not bad

Sturdy metal casing, controls smooth, does what it says in the instructions except the XLR socket screws holding it to the case were stripped and had to install threaded screws and nuts, disappointing.

It does not work well.
At times loses signal.
I bought a second DMX.
