I use this EVERYday. It's small and very easy to use. I tried using it at the office, but it works TOO well!! So, now I use it at home. Lately, I've been using Lemongrass and Tea Tree Oil. My house smells divine. Seriously, it's an amazing product! It has 7 different colors, and I never can choose so I let it stay random. Very nice addition to my home. I definitely recommend!
