I bought this for my son who wears braces. So much easier to floss than the old school method. Saves time and aggravation. Younger son also enjoys using it as part of his oral hygiene. My only con is that the water reservoir is small and needs constant filling. We use distilled water to keep the unit from scaling.
We are pretty unsatisfied with our purchase. The cord makes it impossible to not be right at the sink and the way the water spurts everywhere is VERY messy! Would NOT recommend to anyone.
Treatments for my serious illness attack my bones. My oncologist said I had to be sure my teeth were in the best possible shape to mitigate damage to my jaw. My hygienist said WaterPik would give me a fighting chance. I took her seriously. I am using it every day.
