Title: Quieter model
Review: I have used Waterpik's most of my life with very good results. I am 72 years of age and my gums and teeth are still "hanging on." I think my regular use of a Waterpik has helped my teeth and gums stay healthy.This new model is quieter than the old one I had. It does a good, steady job of pulsating, getting any small particles out of the teeth.The only negative I have is the top storage lid that covers the water container is not as easy to use as older models that hold the pics in the base. Its functions work great.
