Retailing for $60 USD I was expecting some sort of manual & oils to get started..boy was I wrong. This thing has 2 mist settings - a 3 hour nonstop and a 6 hour "intermittent" setting. The light button has 3 options, no light, full cycle, OR you can press light button on whatever color you prefer and itll stay on that color alone. I adore this as a nightlight, but for the price vs other options...check your options before you accidentally buy an expensive "nightlight" with mist features.

Another great one by Sparoom my second one glass. Hard to clean a lot of cleaning and attachments to remove before wiping inside. The outside cracked.

This Aromatherapy Essential Oil Diffuser changes  different colors. This is a plug in unit. It does not have the options for batteries. It beeps loudly at you when you plug in the cord which is a nice safety feature in case it accidentally gets plugged in and you do not have water in it, then you know to unplug the unit or add water. This is easy to use and comes with a detailed instruction booklet. The unt is small and does not take up much space on an area such as a desk, or counter where space is limited. The amount of vapor or cool mist that comes from the unit is not always the same and that is normal. It does not have a constant flow of mist vapor either which also is normal. It releases mist every so often and completely varies. You only want to add the recommended amount of water and 2-3 drops of 100% pure essential oil or you will ruin your unit. It is also strongly recommended to use bottled water such as distilled instead of tap or well water due to added minerals or other things that can run down the life of this unit.
