The Common Scents sells perfume oils designed to smell like top designer fragrances. Their advertising states, "Our fragrances come in pure oil form; 100% alcohol free." Well...they are oil -- synthetic oil. And, they are fragrances, albeit just a hint of fragrance. They claim that their fragrance oils last longer (longer than what?), but they last less than an hour or so. I wish that I had read the Ripoff Report prior to wasting $100 on knock-off perfume oils. The quality of their product is poor and I am embarassed that I was duped into believing that they might be selling a quality product. Sad.
