It did work, and the smell is significantly better. I was dealing with cigarette smoke, but it was not 100%. I’m Basing it on a 24 hour period of time.

Two hours or less after I ordered room shock I found I did not need it. I could not cancel on line so I called your company. The gentleman who helped me left a message for his supervisor of this. I assumed cancelling would be easy as it is with other companies, apparently not!!!!! I will not order anything from you again!!!
