[This review was collected as part of a promotion.] I was using a standard toothbrush until my dentist recommended the Sonic product. As an engineer, I understand the physics of things. The thought of how limited your hand and arm is versus something that is capable of scrubbing thousands of times a second made sense, I am so happy these started coming out and that I started using them and the results show. Limited to no cavities and teeth white as ever. Thank you for producing this product!
[This review was collected as part of a promotion.] The Sonicare 4100 is easy to use and has great features. The intensity setting and pressure sensor helps you to get used to the toothbrush. The two minute timer is very helpful and the battery is easily charged.
[This review was collected as part of a promotion.] I like my new Sonicare brush but my older model was so much better. It had more settings and I liked that the recharging base plugged right into the wall.
