[This review was collected as part of a promotion.] My dentist recommended this product and glad I finally purchased. It is gentle on gums (which I had been brushing to hard for years) and my teeth feel cleaner.
[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.
