It is pretty noisy, but my main problem is that I cannot figure out how to site the Pik Pocket tip. I can't seem to get it between tooth and gum as directed. The general tip seems to work fine.
I have been using waterpik for over 25 years, and love it, I think I am on my 4th one. At one time, I was without one for several years, and my gum pockets got increasely worse. Needless to say say, hopefully I never be without a waterpik again.
As I have gotten older, it has gotten harder and harder to remove food from between my teeth. Seeds and grains like to hide in places that a toothbrush can't reach. My Waterpik flosser does an excellent job of removing all of these.
