The only good thing about this whitening rinse was the taste, it was not bad - almost enjoyable. What was not enjoyable were the results. This was a passive way to whiten my teeth I suppose but I expected there were more results in other methods. I used the rinse for almost a month - that is as long as the bottle lasted, and I saw minimal results. The thing is, this product should be used for smiles that need little or no whitening - or smiles that are trying to prevent buildup.
This rinse would be better marketed as a prevention of non white teeth. It is good to use for smokers, or those who consume red wine, and other things that contribute to the coloring of teeth.
It is alcohol free, I suppose that this is a plus - as well as the sleek and modern packaging. All in all, not worth 14$, go to the nearest drug store and purchase low end whitening mouthwash - same effects!
