I used this product many years ago when I worked for Saje and it worked great then. Recently, I developed a head cold and was so grateful that I had just ordered it and rec'd it a couple days prior to the cold. I use the roller ball end and roll on my sinuses, temples, forehead, throat and behind ears. Releases the sinuses within a short few minutes. Haven't used the other end with the flip tab for using drops in carrier oil. Great product!
