My sink had a foul-smelling odor every time the water was run in the bathroom sink. I purchase Sani Sticks. I don't even remember how much I paid, but it wasn't much though. I came home and put them in, ran water, and the smell was gone. It has been about six weeks the smell has not come back. The water runs down the drain a lot better than it did before I used them. I have them in all of my drains. Love this product.
Bottom Line: Yes, I would recommend this to a friend
