I bought this to help keep my sinuses in check while pregnant. I'm tired of taking medicines. So I thought that I would give this a shot. Anything that changes colors catches my eye and I have to have it. So, I got a breathe and a sleepy time blend for this little wonder. Let me say this... I put in the breathe blend next to the computer desk. It really got the oil in the air and opened my sinuses. I could smell again! Next day I put this oil diffuser next to my bed and I used the sleepy time oil I bought. Let's just say my husband and I sleep like rocks. Nothing wakes us up and we feel super refreshed when we wake up. This little thing makes an entire room smell good!
