I use this occasionally for a few years already.
The feature I like most:
Solid, not too hot (even if it is not leds)
The feature I like least:
Feeling of eternal repetition, one effect, the "Sunflower color" effect is a bit dated and it must be confessed as the title says everyone's tastes, but for electro evening there better.
Medium range, but is still a good value for money.
I use this product with my group of DJs for many years now 2, and the completely adopted.
Actually we walk especially on the "disco-mobile", so we need equipment, light, efficient and fiable.Et this product is light and reliable, despite its simplicity it is working. In fact we have two that we séparont on two feet different light and we head towards the same point. The resulting effect, their brightness and color intensity (in the smoke from the smoking machine) are quite impressive given the size of material and price.
So the price / quality ratio and good, and the product road maintenance, even on big nights.
A remake I buy the same product with the same budget and even with a budget slightly higher (hard to find the concurrency at that price!), And after all depends on the use we want to do, but to get the colored beams and moving to the rhythm of the music, not too light up the room, it's perfect.
