I bought this about three weeks ago and it is the best thing I have ever done for my dental health. I find it so easy to use and my mouth and teeth are already healthier. I had blisters on my gums and they are now gone, since using this twice a day.
I use this twice a day and feel secure that WaterPik provides so much educational information and guidance. I also feel secure using a product whose parts can be replaced -- genuine value and a low guilt factor. I recommend this product to anybody who doesn't have one. (And am now thinking of trying a whitening flosser.) I trust this company and feel fortunate that my dental hygienist recommended using its products when I was a teenager.
