This diffuser is totally different then all my other ones I have. I love the wood like of this diffuser. I like how the top of this diffuser changes colors too. It lightweight and portable. It can run up to about 8 hours. There is also a auto shut off when the water runs out. I like to add a few drops of one of my oils in this and my house smells amazing. It open this different twist it and it will open then take of the inner part add water and oil the close and turn on . It works very well and good quality. I love it and recommend this diffuser .
