I purchased this fragrance for the first time and wasn't sure of how well it would smell or last. Well, I placed two in my house before going to a family reunion and upon return 5 days later I was immensely surprised at the way the whole house smelled!! I had recently moved back in after renting it for a couple of years and you know how renters can be. Because the reunion was so close I didn't have time to do the carpets and therefore just plugged in the oils until I return to do the carpets. This product will make you forget about carpet cleaning and really make your home smell brand new everyday!! Love it and will continue to use forever. Thanks Airwick.
