This is my second waterpik. I bought my first one almost 20 years ago when I had an accident and broke my machine. I love the way it cleans my mouth, teeth and gums and especially cleans my very expensive dental work.
Purchased to replace my older (non-Waterpik) water flosser that had sprung a leak. The Waterpik seems much more well made. I like that I can leave my strength setting as I want and flip switch to turn on. Comes with several types of attachments that I haven't tried yet, but plan on doing soon. The selling point for this model was the glowing online reviews I found and that it was endorsed by the ADA. I'm very happy with my purchase so far.
