Have 2 of these to control usual PAR lights for the band.
Working good for me, and has the needed functions for the use I have, which is DMX control.
For running standalone I would really have liked to have a mode where individual channels can be set to a specified strength, but I have not found that to be settable. There are only "blinky" programs to choose from, which is not optimal for a steady front stagelight.
But with DMX controller it's working great.
