I am a fan of the Waterpik Ultra Dental Water Jet. I now use this product after I brush my teeth with my Oral-B Triumph Professional Care 9400 Power Toothbrush. After I'm done, my teeth and mouth feels immaculate. A few points:1. The Waterpik was shipped in a timely manner.2. I had initial surprise at the new sensation using the 2nd setting.3. First time, my gums were sensitive to the pressure, but had adjusted by the second use.4. Dialed it up to 3 the next day, and going to 4 the third day.5. Easy to use product and knowing how excellent the product is at what is does, encourages me to use it twice a day.6. Comes with two color-coded jet tips for another user.7. Lean over the sink, keep mouth partially closed as instructed.8. No problems thus far (less than a week).I was excited when it arrived in the mail, I really couldn't wait to use it. This product is easy to use and encourages me to use it twice daily!
