WOW, this stuff is great!
I had absolutely NO expectations that this little pen I bought (in a health food store no less) would work. Boy, was I wrong! Have only been using it a few days and have already had a comment about how white my teeth are looking. Doesn't burn your gums, no trays to use and it couldn't be easier - you can do it at your desk at work, in the car - doesn't matter! Like putting on lipstick or lip gloss - 3 seconds, max. And you don't have to rinse it out of your mouth, either - it just leaves a clean, fresh taste. If you look on Britenz's website under FAQ, people say "why is this so cheap???" Britenz responds with words to the effect of "we prefer to say 'good value' rather than 'cheap'." Didn't think there was anyone left selling a product that really works and not jacking up the price for every buck they could squeeze out of people! It's only been a week or so but I now cannot imagine life without BRITENZ. :)
