I work with essential oils daily, and I have diffusers going in many rooms of the house. This is a really beautiful one, that is pretty large. It doesn't hold a large amount of water and the compartment is pretty small, so you will need to refill often. Make sure you do not refill past the maximum level line or it will not diffuse properly. You have different settings for colors that you can have it on or set the timer. It comes with an actual wall plug for the socket versus a USB type plugin. ISee full review
