Great diffuser. Great price. It's a nice compact size and the lid is easy to lift off with one hand (compared to the kind that have a tapered top). Holds a good amount of water in the reservoir.
You're able to have the diffuser running with or without the light. You're also able to set the colours to rotate through the spectrum, or choose a colour for it to remain on. My daughter has fun deciding which colour to choose. It's great as a nightlight too. The light can be used independently of the diffuser.
Lastly, the diffuser settings allow for constant or intermittent. This really helps the scent last a long time. I don't need any more diffusers in my house, but would totally buy again otherwise!!
