I love this diffuser that much I bought another one within a week for a present. It's so easy to use, a great visual piece to the home with the ability to have all the different colours cycling or pick a particular colour to go with a particular time of day and or mood that you want to promote. Strong mist is great to start with and then I find the low mist is suffice for a bedroom. I love the timer & auto off feature as well. I will definitely buy more from Asakuki for presents. To be able to give a present that is fun, great centre piece with great aesthetics and most importantly beneficial for your health, it's a win - win. Footnote: it's important to buy natural oils and not synthetic oils.
