I have always liked the Listerine run of products so when I saw this one show up in our local B.J.'S Club I decided to get some. They came packaged in two's for about ten dollars. I have been using it now for about a month and it does seem on the strong side but I cannot say that it has a bad taste to it at all. It is supposed to take care of several dental concerns at the same time and I could tell that my mouth was quite clean after using it. For what it does my impression is that it is money well spent. Dental health is quite important and its not an area that one should try to take the cheapest way out. Its been my experience that Listerine products are quality. The recommendation is to use this product twice per day. This product came in the 1.0 liter size. The flavor of this mouthwash is mint. I have tried several different types of mouthwash including some of the cheaper one's and so far I really do like this one the best out of them all. I will continue to use this one as I feel it is the best overall choice although certainly not the cheapest in price.
