I've had this summer and it is nothing but a smoke machine ...

For those who use slave, the fog machine is issued by that extra.
it is capable of filling a room large enough size in record time and above all maintain that the beams are visible throughout the room (not like with smoke).
The difference is in the fact that customers no longer feel "attacked" by a jet of smoke, dense and compact ...

Nothing to do ...

Consumption ... a bottle of 2.5 liter four evenings (weddings)
