I am happy that I purchase this really nice aromatherapy diffuser. I loved the 7 changing colors! Super easy to set up and use. It's beautiful and I love being able to move this diffuser from room to room. It can hold up 400ml water and run for up 8 hours to 12 hours, and has 4 timer 60/120/180 minutes/Continuous modes. There is barely noise. It is so quiet. I like that it auto shut off. I put a few drops of stress free fragrance into the diffuser and now my air in my room smell wonderfully. There are three in one function: 1: aromatherapy diffuser, 2: it a humidifier, and 3: It is my night light as well. I really recommended of getting this one for yourself or a gift. #rankboosterreview#sponsored#ottbox https://www.amazon.com/Aromatherapy-Essential-Diffuser-Humidifier-Shut-off/dp/B06X9G4N3C
