I've bought these when they came back to "shelves", the shipping and payment was fast as usual. Upon recieving and testing it for a day, i've figured out that three of heads were not calibrated on tilt position propperly (could not fix it with calibration on head also) :S After contacting Customer Center, explained problem, and after 5 days, i already recieved two heads and after 3 more days the last one. This time heads are working as expected. I'm impressed with light output, if you compare it for example with 70w led par at full intensity, the spot will still cut through. Comparable with other moving heads i worked with, this one is really not making alot of noise, and its also very light and small, which is perfect for small stages and limited space in trailers. Tho i haven't found highlite cases on thomann site for these yet which would come handy, so i think i'll have to search somewhere else. Perfect head for small stages, still features quite alot of stuff for gobos, prism, colors, etc. Auto programs like usually aren't very usefull but with DMX this becomes great unit.
