VERY SATISFIED
Style: Haze 4D
So far very happy with this purchase. I have it daisy chained via DMX with 10 YeeSite lights and it works great. Produces an amazing amount of haze for its size.

Truly is too good to be true.
Style: Haze 4D
Looks nice, and it is a great product, but the internal fan has already quit functioning. Not some thing you expect from a brand new item. Before it is assumed, this item stays stationary. We don't move it, and it is used on a stage for a 1800 capacity venue. We don't buy garbage fluid for it. We get the suggested type from Guitar Center.

Wobbly
Color: Grey
Wobbly and the metal bars keep coming off. Be aware. I’ve tripped over them. Be careful.
