I purchased about one month ago. Nver used one prior. Got the black model! Love it. Gums seem healthier and teeth are smooth and clean! Got one for each member in my family!
A friend gave me a water pic for Christmas and I have been using it daily. Am very satisfied with the results and my teeth and gums feel so much cleaner than by flossing alone. Wish I would have bought one years earlier.
Found a new dentist, she advised early stage periodontal desease with gaps up to 4. Bought a WaterPik, followed her presription, checkup today - all better 2s and 3s. Will use it for the rest of my life.
I have been using Waterpik for over 12 years and my gums have gone from bad to healthy! The unit worked fine for 12 years of twice-daily use plus a fair amount of abuse. Finally I got a new one and I expect another 12 years. Get one, start with a low intensity setting, build up to 10 over a couple weeks, and your gums will be healthy again (plus your mouth will be cleaner than ever)!
