I just bought two and I'm very satisfied I can not comment on the quality I vair good time. But for now I think the quality is very good.
The brightness is comparable to that of the example MAC 250 Krypton. The two gobo wheels allow multiple possibilities, not to mention the prism.
The RateMyResort:
_Solide And robust
_Exelente Brightness
_Nombre Possibility (2 gobo wheels, a color wheel; Frost; prism etc. .....)
_The Design (she really out of the mouth)

The Poins Low:

_défaut prism (beam of light so the side, this is not very serious but still!)
_A Little too heavy! (24 kg)

Here is a summary of a good product with a flaw! But good overall this lyre is very satisfactory and I recommend it because the price is interesting!
