Playing Rockband is just not the same as playing with Fog and lights. This unit it AWESOME! It really takes the game to a higher level. I have a projector screen set up in the basement that we play on. Even with the doors shut, this fogger fogs the entire house! and WILL SET OFF THE SMOKE ALARMS upstairs. I could not imagine the amount of smog this would creat in a small room.
The Fog has no smell and does not seem to leave a residue.
