We have been using this wonderful product for almost as many years as it has been for sale! We love it and it has really changed the condition of my teeth and gums for the better. I would be lost without it.
The only problem I have had is that over time the tips lose their shape and fly out from the water pressure. We have bought new ones because of this and find that the old tips do not always fit the new connections. But over all these years the price has not really gone up as much as would be expected. We have bought it for our adult children and everyone absolutely loves it.
