I have 2 devices for about 4 / 5 years, bought during a promotion that provided them with transport case.
Pros:
* The size (4 projos in one).
* The simple DMX controller or each pilot channel at a color contrast or color that I almost anything.
* The power light, blue and green are beautiful and very bright.
* Certain color combinations are interesting.
* The angle of illumination or too wide or too narrow can illuminate the scene and not the ceiling or behind the scenes.
* The rapid establishment: placed or hung, the outlet nearest (2000W total attention is 10 A per unit!) Connect the DMX and that works.
* The circuit breaker incorporated.
Cons:
* Lamps expensive and fragile.
* Yellow is a bit greenish.
* Red lacks a bit of tone.
* The bushes are fragile ..
* No preheating
I use them often for an orchestra, concerts, shows, dances ... this is a practical and versatile product, ideal for small scenes. for large scenes, do not révont with 500W per color, you need to put more than two. I had only one fault: the transformer of the electronic equipment has dropped. It turns out that the design, it is too tight. I replaced it with a more powerful.
I plan to buy two more.
