The device was delivered very fast and was neatly packed. I've been running the dimmer pack in DMX mode ie with a fixed address, dehalb I can not comment on the programs already saved. In DMX mode, it does exactly what it should. For performance, I can say that until now does what it says because I run 2x 1000W and 2 x 500W spotlight on it. Unfortunately, the device is not as high as I would have imagined for around 80 (which does not mean that it is bad Quallität) about -1Stern Nevertheless, a great part and it would buy jederteit again.
