This is my first time using an electric brush and I have to say my life has been changed! This product is incredible, my teeth have never felt so clean. I also like the fact that it’s super easy to use and really affordable. Carla · walmart.com

This is the third Waterpik brush/floss I have purchased. The first one for myself, then one for my cousin, then the third one again for me because my first one stopped working after 4 years. I love this product and do not see myself without it. I am shocked that other companies have not followed suit in creating this type of brush/floss all-in-one toothbrush.
