Definitely will buy again.
I really can't tell yet if there is a long lasting effects from using this. I can only detect that my smile looks brighter immediately after I use the product. Since I consume caffeine products all day, anything I can do to fight the stains helps. I liked it well enough to recommend and buy for my sibling. I will repurchase this product.<br /><br />BTW, no discernible horrible taste. It has only the slightest charcoal smell. I am able to tolerate the smell and taste well. As I said, I will buy again. I will probably try one of those DIY projects with Elmer's glue and try to make a face mask to use instead of those expensive nose strips.
