I am so happy to be sent this essential oil diffuser as it looks so great in design and I have it by my desk. The output is fantastic. I have owned diffusers that have such a low output it is hard to enjoy the scent. This one works great. I love how long it will stay on and diffuse-up to 8 hours! There are so many color-changing options and stays cool to the touch. It also comes with a free peppermint oil that smells so great!
