I had a problem with the WaterPik I purchased. It was defective. Customer Service took awhile but they replaced it with a newer model. My teeth really love this system.
Great way to brush and floss without having to floss. This waterpik toothbrush and water cleanser in one is the easiest way to clean your teeth while brushing and using water dispenser option to clean between your teeth to remove tarter buildup and any leftover food particles too!! Much less time than flossing after brushing and you can increase the power of the water for even more effective cleaning!!
