This review is from: Waterpik Whitening Power Flosser (Personal Care)
Have to say it isn't as effective as manually flossing as it doesn't seem strong enough to get between my teeth that are close together! Good for the gum line as design makes it easy to get into back of mouth but teeth don't feel nearly as well done as when using string floss.
