[This review was collected as part of a promotion.] I have noticed a big difference with how my teeth feel. It certainly removes the tartar and my teeth actually look whiter. It is easy to hold and it gets at your back molars very easily! Mell
[This review was collected as part of a promotion.] It seems great so far (few months). I like that it’s compact and the brush is soft. The battery lasts a long time between charges.
[This review was collected as part of a promotion.] Especially compared to earlier versions of Sonicare, the 4100 is light, comfortable and effective. The smaller brush heads are a plus for reaching back teeth, and charging is more convenient than earlier versions.
[This review was collected as part of a promotion.] This is my first experience with an electric toothbrush. It was recommended by by new dentist to ease the stress that regular brushing has on the gums. I have been using it for two months and it seems great. However, I really won't know until my next dental appointment if it had a positive impact.
[This review was collected as part of a promotion.] I updated from an older version and appreciate the slimmer handle. I did not appreciate that I needed to purchase a black to charge it since it came with a USB cable only.
