Have you tried the new Colgate Wisp? I must admit my skepticism when I saw the commercial for this product. How on earth can a toothbrush work without water? After visiting my favorite mass merchandiser Target a few weeks I decided to purchase. The foil sealed packs are so compact you can store in your handbag. I am a coffee drinker and for as much as I love coffee I dislike the aftertaste. The Wisp proved to be the best product for eliminating this aftertaste. During lunch over the weekend I found myself eating a salad and having lettuce stuck in my front tooth. Guess what I forgot my Wisp. My suggestion is to store in every handbag so you are never without them. These are must-haves!
