[This review was collected as part of a promotion.] Great toothbrush. Less is more. I don’t need my toothbrush to talk to my mobile phone, nor do I need multiple cleaning modes such as polish, gums, etc. Battery life is in excess of two weeks, but I expect that will diminish over time. The alerts for time and pressure help in ensuring proper cleaning of teeth. The units last a long time. I believe this is my third one in close to ten years. This 4100 cleans just as well as more elaborate Sonicare units that I have used in the past.
[This review was collected as part of a promotion.] Sonic 4100 has surpassed my expectations! My teeth are cleaner and whiter than I had hoped for. Easy to use and I am happy the battery lass two weeks or more.
[This review was collected as part of a promotion.] As always, Phillips produces a solid product. I purchased this on sale from a big box store near me. The C2 brush head is just too small for an adult. It is better suited for a young person.

[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.
