Aroma Diffuser creates a relaxing, fragrant environment at home or in the office. Simply fill it with 150mls of water and add a couple of drops of essential oil (not included) which will produce up to six hours of continuous operation. It is powered from a USB port or a mains adapter and has a soothing multi-coloured ambient lighting option. Aroma Diffuser is presented in a white box along with a Micro-B USB cable and an instruction leaflet.
