This is a nice large 500MI COSSCCI Essential Oil Diffuser. It can run up to 10 hours depending on what setting I am using. On high it lasts about 6 hours and on high 10 hours. I can set it for 60, 120, 180 minutes or continuous. If I choose to use continuous I don't have to worry about it running dry because it has an automatic shut off which is great because I wouldn't use that option in fear I'd forget to shut it off. I usually use the continuous mode unless I know I'm leaving my home shortly.
I like that it comes with a remote so I can adjust it without having to get up if I'm comfortable reading a good book. This put a nice cool mist in the air and come winter when the wood stove is going the air gets so dry and this will help put moisture in the air while making my home smell good at the same time, not to mention the beautiful look of it running with the bright colors changing. It has 7 different colors and they change from one to another or I can pick my favorite and set it on that color only. I can also use it as a night light without the mist too. If I don't want the glow of the light but want the cool mist I can do that too.
This comes with the diffuser humidifier, wall cord, measuring cup and remote control. It comes with everything needed to operate the diffuser, well except my favorite essential oil. When I want to make my house smell good I add 6 to 10 drops of my favorite essential oil to the water. This is would make a great housewarming gift or a Christmas or birthday present too. I recommend that anyone who buys this product to read the manual to learn how to fill it properly so as not to damage it and how to take care of it so it will last a long time.
