[This review was collected as part of a promotion.] The 4100 does not work properly. This is the second one that I had it won't vibrate when brushing. I do not recommend this model. With that said Philip did replace it with the 5100 and there is no comparison in brushes. Highly recommend the 5100 series.

[This review was collected as part of a promotion.] The only thing that sticks out positively is the price. The strength of this toothbrush is weak. No power in the toothbrush. If you follow the guidance of the machine for when you brush too hard, you would barely be touching your teeth, let alone clean them.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] I had a similar item before, but the battery finally died. The new one is a great replacement and even a bit smaller in the hand. Good product!
[This review was collected as part of a promotion.] This is an incredible toothbrush, I find it does a great job cleaning the teeth. I found my teeth getting white and gums are healthier. I would highly recommend this toothbrush to everyone.
[This review was collected as part of a promotion.] my dental hygienist suggested it, but it doesn't do a thorough job. When done using it, there is still stuff left behind between teeth
[This review was collected as part of a promotion.] Does the job, not as powerful as my last one from Philips. Do not like fact that the mode indicator is not on this model.
[This review was collected as part of a promotion.] I have owned Phillips electric tooth brushes for years and have always liked them very much. My complaint about this one is that it is not textured and is very hard to hold onto. Please go back to making them textured.
