Lets just say it caused extensive damage. Many house fires have been attributed to these devices. Now they clame they are making them better these days but i just don't beleive it. In my home its a no go, no questions asked. You want a scent burn a candle and even that had better be attended! im alittle crazy when it comes to the fire prevention i have just seen so many bad calls in my days. It wakes ya up. Many of the fires today are attributed to what, electricial in nature! so im extra cafeful in my installs. Hope the helps ya out electricman scott.
