I have received the toothpaste to test and have to say after 4 days, the teeth are much whiter. You feel after brushing also much smoother and cleaner. I drink very much like coffee and tea, this can be seen also on the teeth. Particularly the canines have with me always be slightly discolored. This is however almost completely disappeared with the blend-a-med. The toothpaste is nice and fresh but not too spicy, it lathers well on what I personally like very much. Man can use it well with the electric toothbrush. I can only recommend this toothpaste.
