To smell: Smells really like any other fog.
For mist itself: Had my fogger grade times 10 seconds ignite the entire apartment (80 square meters) to be filled with fog, so really extreme. The fog keeps 20-30 minutes at an open window approx.
Conclusion: If you want to have really thick, good fog, and often not the fogger want ignite for wages, this fluid absolutely!
Ps: In this fog can be seen Laser and LED effects better, as in the standard or professional fog!
