This is my third one. I place them in various rooms when I need to. I use it in addition to a vaporizer when I want a quick and easy solution. If my cold is worse then I use the regular vaporizer in the night time and use this during the day.
Helps when you are stuffy and congested. Just plug it in and place a small tab in the holder. It has 3 settings and the menthal aroma fills the room in a subtle way. I love this product and find it helpful when my 8 year old is sick as well.
