I purchased the Redolence Nebulizing Diffuser during the 2018 Black Friday Sale. I had originally looked for a Diffuser when I came across these Nebulizers, a whole other tier for the senses. To date I don't regret the purchase. I've experienced many scents from around the world brought to me through a bottle. Patchouli is one of my favorite scents, please give it a try. To clean your nebulizer just follow the simple rules as stated on the website, its a breeze.
