This is a very good product to clear your nostrils. Since I have very bad allergies, it helps get the mucus away. The instructions are very easy. First, just prepare the saline solution and put it into the pot. Tilt your head and put the sprout into your nose. Raise the pot slowly to and let the saline solution into your nose. Remember to breathe through your mouth. I would definelty recommend this product. But if your nostril is a little smaller, this product not be right for you.
