I use it for 5 years or even more, never a worry, I never try other models I plug it in 4 56, inconvnient he do that 4 outputs. Easy utilisastion I use it in manual and non-music with the microphone, many programs but I use 3 or 4, I love it when two are in turn at the same time.
I would do this choice because otherwise need to invest in large tables of control but better switch to DMX.
