I have only used this product for about two weeks. My teeth look and feel cleaner. Can't wait until I have my next appointment with my dental hygienist to see her reaction.
I love using my Waterpik. I have had it about a month. I left it at my daughter's house while visiting a state away. I had to ask her to FedEx to me as I couldn't live without it. it helps my mouth feel so much cleaner and my gum health is improving.
the storage case is a little awkward, you have 6 brushes and only enough room for 4, and is a little hard to get at, but I do like the brushes themselves.
