[This review was collected as part of a promotion.] Dentist recommended. Waiting for my next visit to see if it really makes a difference with plaque removal. Was annoyed that I had to request an adapter for charging plug. If you aren't going to supply it with product it should clearly be stated. Since you supplied it for free upon request, it should be an option when originally purchasing toothbrush.
[This review was collected as part of a promotion.] Great features. Like the 2 speeds and overpressure warnings. Change brush alarm hasn't activated and brush looks ragged. Would recommend.
[This review was collected as part of a promotion.] My second Sonicare toothbrush that I have owned. There are a better selection of brush heads for the 4100 than I had for my first Sonicare toothbrush. The 4100 is affordable and good selection as a toothbrush. My only complaint is the audio indicator between 30 seconds intervals could be more obvious.
I read the reviews on the other toothbrush offerings and I decided on the 4100 as my choice over the others for the following reasons. Less technology means less things to go wrong with it overtime. I’ve read that and agree with the 4100 will clean just as well as the more expensive offerings. I’ve only had this 4100 for a short time, but I am well pleased, though at first, the tingling was somewhat interesting to say the least. I got used to it rather quickly and I feel that my mouth is very clean. I have a friend who is a dentist and he has the Phillips toothbrush as well and recommends it.
