I have used a WP for many years. Even took a smaller battery unit on our two month vacay this summer. Original died, got a replacement. Wife is now using after dentist asked if she had access to one.
I can’t live without it. Comes with many tools but I favour 2. I bought travel one too. Unbelievable what still expels from between my teeth, after I floss and softpik. You don’t wake up with yucky jungle breath. I’ve worked in a dental office for over 35 years. Listen to me. Your hygienist will love you.
It is too noisy. However it is quite easy to interchange the heads.
I would recommend this to a friend!
Response from waterpik.comBy WaterPik, Product Support, September 11, 2019
We are sorry you are not completely satisfied with the model. We elected to make a change to our Water Flosser products to be more compliant with energy efficiency. The change included changing our motors to a high voltage direct current style, reducing the wattage consumption from 34 watts to 14 watts while still generating higher pressures. The new high-efficiency motor is lighter, and may subsequently produce a louder motor sound when operating.
