Got this on a whim, trying to have natural scents in my home and not toxic ones. I have it in a bedroom and it works well providing the scent in there. Easy to use and so far no problems after using it for a week. I like that you can change the color settings or no light at all. Things I dont like, I wish there were a bigger one that holds more water to run longer. I believe it runs about 5 hrs before shutting off. Other thing I wish it had was a timer to run in intervals not just straight running. The run time would probably last longer if it ran in intervals without a need for a bigger tank. Overall I am pleased with the product for someone who is just starting out with diffusing essential oils. And I purchased a second one to use in my living room. Hopefully it will provide a strong enough scent to fill a room that is a little larger than a bedroom.
