Just be careful if you plan on using it at weddings. Chilled fog is very different from a professional low-lying blanket effect as produced by a dry-ice based machine like the Pea-Souper as shown in the photo below. The dry-ice effect will stay low and dissipate into nothing while the chilled fog will slowly rise causing camera flashes to bounce back and ruin photos. The effect in the photo was not produced using a Pea Souper rather a huge professional device that utilizes a CO2 gas cylinder like this one: http://www.starlight.com/lsg.html
The effect was subbed out to a local company. It required a good clean 15 amp outlet to run it as well...
