I use this product for 2 years before this one I have used nothing else. This effect is great because it has many gobos and a multitude of colors. Perfect use for a large room or outdoors. I did not like it weighs 9kg and its handle for hanging on a ramp because it is not the center of gravity of the aircraft causing it to constantly switch. stormbird but is really a great device with a reasonable price, and if I go back I would have made this choice because I do not regret it.
