I've had this model for several years and it provided good service if you follow some guidelines:
Keep the tank at least 3/4 full of fluid
Let it warm up several minutes before pumping (when it smokes, its ready#
Do not try to pump too fast or you will squirt a stream of fluid, not fog
Use a sweeping motion on a windless day
Clean out the end of the nozzle occasionally with a wire to prevent soot buildup and eventual coil clogging
Do not store liquid in the tank after use
Short propane bottles work as well as the long ones
Finally:
Wear hand, eye and breathing protection #use a good mask, not a paper one)
Keep pets away from the area until it dries
I am about to get a new one since the last one was stolen. I only rated this a 3 because you have to fiddle with the gas bottles, lighting it, cleaning it, and so on. It's not a pick up and use tool, but better than sprays, candles, giant bottles killers, or those stupid neon light things.
