These cute steam diffusers, available in 3 different colours with colourful lights, have 2 modes, a continuous spray and an indirect spray, dictated by one key switch. Simply take the lid off, add water to the tank along with as few or as many drops of fragrance/essential oil as you want, depending on how strong you like the diffused fragrance. Then, plug it into the power supply, & turn it on to have the fragrance released into the atmosphere, making your room smell gorgeous.
