Purchased about a month ago....takes a little practice to get used too, but it cleans your teeth and gums very well..I had particles to come out of my gums even after brushing!!! Very powerful, I haven't used the highest power setting yet, due to strong pressure.
This is my second Waterpik and I totally love it. When my old one died, I immediately ran out to replace it. It finds food you had forgotten you had eaten and washes it away and replaces it with a nice fresh feeling. Add a little mouthwash to the water reservoir after you have brushed your teeth and you will think you had just completed a dental hygienist visit.
We have been using this for about 2 1/2 months now and really love it! It is super easy to use and seems to be working well on our gums. And it is a perfect size for our bathroom countertop and really easy to maintain. VERY happy with this purchase!
I love this product! It does not replace flossing but it is an amazing invention! I use it before I floss my teeth and it gets most of the nitty gritty out!
