Terrible No, smell barley works [SEP] This is the 1st one I bought, and it is junk. The only way you can smell anything is to put your nose up to the opening. It is quiet because it barely works. I was not impressed with the oil that came with it either. I now have 3 others Not this one, that work perfect. I don't think they cost as much either. Do your research. The only good thing I can say about this unit is that the light show is pretty.
