Review Content Great diffuser! I use the product daily and it fills my apartment with the amazing scent of Puzhen essential oils while looking beautiful. Love this diffuser I have 2 of these and use them almost everyday. I love that they can be set to diffuse for 4 hours, which is great for using at night. My go to diffuser This diffuser is great! My only complaint is that I wish it was smaller, but maybe it wouldnt cover as much square feet at a smaller size. I use it on a daily basis and have had no trouble with it. The controls are easy to use and I love the fact that I can set it on 1 hour or 4.
