Excellent product

[This review was collected as part of a promotion.] I was blown away the first time I use this product. My mouth has never felt this clean without going to the dentist. It takes a little getting used to, but by the second use I will never use another type of toothbrush.

Great product & reasonably priced

[This review was collected as part of a promotion.] My Periodontist recommended this series when I was telling him I need a new Sonicare. Usually I get the more expensive ones. This one is so reasonably priced, has the 2 minute timer. I like the simplicity of it, no grooves on the handle and easy to keep clean. Gets the job done, my teeth and gums always feel clean!

[This review was collected as part of a promotion.] I bought this for my wife and I have had one like this forever. This is mine and hers favorite and we will continue using this product in the future. I have bought my children and grandchildren one of these and as for as I know they still have one.
