I've had GREAT results with this toothbrush!
I've been using this brand of electric toothbrush for over 10 years now. I originally used the one with the "sensitive" setting. However, that one (I purchased in 2020) ended up getting bent (I don't know why), so I had to purchase a new one. I couldn't afford to continue buying the one with the sensitive setting, so I bought this model. It is good & so far is working great for me.
Pros
Great dentist results
Cons
No sensitive option on this model

We love our Sonic electric toothbrush!
The Sonic toothbrush is far superior to any other electric or manual toothbrush on the market today. I have been an advocate of Phillips Sonic for over 15 years, both my wife both have the same models and we use them twice a day.

I like the 30 second tones
Performs as advertised. This is my third of this brand. When one wears out I buy a new one.
