I bought two scan SM4 almost 2 years ago.
Ds the first use, one of the two was a dcalage color. I had half a color instead of a whole. Then came the protective sheath of the mirror Cables began to melt.
Then, the color of dcalage has worsened! adcalait a time of 6 color! (The other scan works well) Then he started to do the reset during the show (always the same scan that DCAL colors). The shutter started to beuguer (half closed or strobe o instead of being open and not quite closed in black out).
I sent the scan dfectueux for service and it made me not much better than before! Since the two scans have been a shit, all gobos are oxide and color filters have split! The last time I've used the mirrors were just shaking, the color wheel turned back and made shutter strobe! I could not control them!
In addition, the brightness is mdiocre! white is yellow ..
A by a gobos are pretty and the colors too.

If I had the choice again I would not scan this brand! (I have now invested in four Robe Scan 250XT DJ and deifference was not built to wait!)
