I was able to test it during my internship at DMX Pyranime.
I have not much to complain about except that the gobos are not always very clear otherwise say a hot spot that is probably too strong of the lamp used and some gobos are a little "squeaker squeaker" (3 or 4 of 11 so it will) I really like the other electronic dimmer which vary the intensity of the lamp.
The product is a bit expensive but very complete and well made.
I put 9 because some gobos I do not like too
