The Aura Ultrasonic Aroma Diffuser is the first aroma diffuser to house three separate essential oil chambers in one device. Users are able to blend oils together to create their own unique fragrances, which in turn allow them to create their own unique home ambience. The essential oil combinations are limitless and eliminate the guesswork that goes into finding the perfect blend to relax with. Built-in color-changing LEDs and a 5W Bluetooth speaker also help set the mood to create a one-of-a-kind experience.
