I bought one for my daughter since she just got braces, it works so great on her braces that I bought one for myself as well. I hate flossing and this makes flossing great!!
I bought this a month ago, because my daughter got braces. She loves it and uses it all the time. I just bought myself the cordless water pick and I love that one.
I have used a waterpik for over 10 yrs. when gum problems started. Since then my gums have not worsened. Also, my dental hygenist constantly compliments my dental hygiene. I Would never be without my waterpik. Thank you waterpik!
the wp-100 works very well. getting used to it didn't take long since i already have a wp30 that still works fine, but can't get tips for it. Anyway, hope the 100 proves to be as durable.
