I use this material recently. I bought a pack of 3 down and have repaired 2, the 3rd room left for.
I find them quite slow, not very accurate, no memory of position and not turn off the light before turning off the unit.
Consuming maintenance, cleaning difficult, high weight comparable to a light 200MSD
For the price, I will not complain, 2 color wheels and gobo wheels 2 with a rotating gobos including 3 glass gobos. 3-facet prism a Zoom and Iris makes this fairly complete unit.
Depending on the price, it should not be a deal or not
