I use the Sonicare Toothbrush everyday. I feel as if I have just gone to the dentist and received a thorough cleaning, the effect is that good. It does take a while to get used to the toothbrush at first. The oscillating head moves extremely fast and at first it felt like it was really vibrating in my mouth. It has also felt like a jolt or like a tingling sensation when I first started using the Sonicare Toothbrush. After a few uses my body became used to it and it felt fine. The Sonicare Toothbrush is relatively quiet compared to other oscillating toothbrushes that are on the market today. I like the fact that there is a charger that comes with the product. Usually after about 20 uses the product needs to sit on the charger overnight for it to work at maximum performance once again.
