This seems exceptional but I wonder about the issues some others have talked about here.
This seemed very well made and like it made the whole room smell clean in a way another brand I have does-telling me that it may be one of the best kind I can buy.  Then one day no long after I got it I dropped in on the bathroom tile floor.  It will not light up any more so I am sure it is broken for good. I did try to fix it but was hesitant because of the few warning labels on it that I didnt understand.  It said something like, "if your going to try to fix this work on the whole thing or you will ruin it for the purpose it was intended." I was done after that.
