I had bought the Waterpik Sonic Fusion 2 for my husband because I have had one for over two years and love it. My husband loves it too! He is happy that he can floss and brush his teeth with one device instead of using two separate ones. The Waterpik's flossing feature works very well, and after using the brushing feature, he says his mouth feels fresh and clean. It's also light and portable and he is planning on taking it when we go on our road trip in a couple of months.
