I love Marvis toothpaste but find it a little more costly than I'd like to pay. This mouth rinse is actually nicely priced considering one can mix it himself. I think 1 part Marvis to 3-4 parts water works well. The taste is mild when swishing and seems to be more invigorating once I spit. While I love the packaging, it is kind of sloppy to pour the rinse to mix with water. I'd also like to see them test out different flavors...like maybe cinnamon.
Pro: great packaging, cost effective
Mod: masks breath for short while (not really any less than others), bottle could be larger
Con: could use a dropper for mixing
Very nice product!
