I bought a Waterpik Ultra a couple of weeks ago and absolutley love it. I use an electric toothbrush but hate flossing. I realize that its important to floss but always find it a chore. The Waterpik has made cleaning away the bits that my toothbrush miss a dream. My mouth feels so clean afterwards and my teeth are becoming whiter too. Using it can be a bit messy as its important to let the excess water drip out of your mouth into a sink. After a bit of practice, this isnt an issue, and its great..
