Love it! Love it! Love it! As a buyer of 3 other ‘oil diffusers so far this year and one costing over $80, this one has been the least expensive and so far the best by miles. The greatest feature being tank size which is just what I needed to diffuse frankincense , lavender, and peppermint all day and night long!!!! Such a relief not having to top it up several times a day - fill it up once and your set! and where my other oil diffusers have been quite small the flow of mist has also been quite thin but the stream of mist in the ASAKUKI is perfect too. If I had to really really be picky then the water cup suppplied is tiny in comparison to tank capacity - but put it aside and use your kettle or jug or water bottle and away you go. Everything is pretty straight forward to use , the lights are lovely but you don’t have to have them on if you don’t like them or are sick of the sight of them after a few hours. If your going to buy an oil diffuser this is the one to buy and delivery was super speedy too!
