First of all...
fans let's say medium noise level, can live with that on the private parties
for the features and light output if we talk on price/performance ratio very well, if we compare robe fixture - long way to go.
about the quality....
can't say anything good about.
1) adjustable PVM? 25k is still hitting your ears with high frequency.
2) almost all heads had transistor fails before led.
3) optics between leds and lenses will burn. i guess we'll have one fixture soon.
4) if we look on symetrical side we have few heads that lenses center is not in the center.. is that defect?
5) some times need to reset fixture (lenses rotation). just loose their position
6) handles? hmm, feels like someone: ok, 21st century, go modern ways. remove that. that's not that bad, but c'mon +5 work speed on rigs.
7) 40w on each eye? feels like more about up to 30w
repairs are kind of cheap if you what you doing, but repair heads after each event bruhh.. think about that
