I've had several atomizers, diffusers, and humidifiers. This one turned out to be the best priced, most convenient, prettiest one I've owned thus far. What I love most about it is the ease of use. Unlike most diffusers, it's very easy to fill and clean, and doesn't require me to constantly unplug it.
However, if I DO need to unplug it for cleaning, the plug can be removed from the device so there's no need to fish around to unplug from the wall.
I use this for sleeping, so I don't use the lights, but they can be turned off and they STAY off, no need to turn them off every time I turn on the device, which would annoy the crap out of me.
It's a great purchase, just keep in mind it's small and won't run all day.
