The simplest statement is the best in my view. This product does exactly what it is designed to do. Great features with the brushes, cleans the teeth and exercises the gum lines, and removes food from in between teeth.
I bought this item a month ago and love it. I brush with an electric toothbrush and thought my teeth were getting clean. Using the pick after brushing forced large pieces of food still trapped. I couldn't believe the difference. Love it.
