Own quite a few of this model, as it's hard to find good quality side venting mist diffuser. This combines large water capacity, beautiful design and quality. It covers large areas beautifully and you can adjust the mist level to suit as well. Like all asakuki products this diffuser retains essential oil much better and longer than others meaning you'll smell the essential oil all the way until the water finishes. Don't let the price fool you, it is cheap but it is very high quality and high end with awesome finish. I've spent hundreds on diffuser before but non compared to this. This is My favourite!
