Makes my teeth feel cleaner and look whiter

[This review was collected as part of a promotion.] This is the first electric toothbrush I have ever had. I was amazed after the first time I used it! My teeth felt like I had just had my teeth cleaned at the dentist's office! After using it regularly I have noticed my teeth are much whiter than they were before. It took me a little while to get used to it, but now I am hooked! I absolutely love it!

LIGHTWEIGHT; EASY TO USE.

[This review was collected as part of a promotion.] I LIKE THE LIGHTWEIGHT DESIGN AND EASE OF USE. THE RESULTS ARE EXCELLENT. THE CHARGER and THE BASE DEFINITELY FILL and HOLD THE CHARGE FOR A LONG TIME. I WOULD LIKE TO SEE A LONGER BRUSH THAT FITS ACROSS THE TEETH LIKE THE OLDER ELITE MODEL FIT. I'M GLAD I PURCHASED THE ITEM.

[This review was collected as part of a promotion.] I travel. And one charge lasts about 2 weeks. The shape is comfortable in my hand and the control button is easy to use. I like the brushing timer and that I can choose to use it or cancel it. And the unit, as a whole, does a great and comfortable job of cleaning my teeth. This is reflected when my hygienist doesn't need much time to do my semi-annual cleaning.
