Great product to use to keep my teeth thoroughly clean. No need to over brush with the timed pauses that lets you know to move to another section. Also a great way to clean the tongue.

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
