I bought a Gobo Flex less than 4 weeks ago. At first I thought it worked pretty well. But it wasn't as good as I thought it would be. All was well except the mirror movement. I thought it would cover area, but it only went side to side, and it got annoying. The optics of the gobos weren't that good when the mirror moved, and you couldn't really make out what gobo it was when the mirror was in movement. Another thing I didn't like is that the mirror stops at a bunch of different places without doing a full side to side sweep(all of a sudden it stops and goes the other way without doing a full left to right/right to left sweep). And sometimes it would only sweep on one side, and it chopped back and forth like something stopped it from moving to the other side. I sold it 7 days ago to a local DJ, and bought a ADJ DJ Scan 250 online for only about $60 dollars more than the Gobo Flex (without shipping). The DJ Scan 250 is way way better it has excellent optics, and movement all around. I highly recommend the ADJ DJ Scan 250.
Hope this helps you.
