I just moved in with two friends who have been avid users of diffusers for some time. And, I should add, both are passionate promoters of Saje and it's products. Through them I've come to really appreciate the benefits of aromatherapy and so I took it upon myself to by my first diffuser. This product is amazing. It's a stylish work of art and besides that, it works miracles in my life every day. I don't know how I got along without it. I love the two tanks. It's great to not have to wash it set it all up again for the evening. The timer function is also awesome and so simple to use. I've gotten rid of my beside alarm clock, and just use this now. It's perfect! Thank you Saje.
