But It!
I was initially skeptical that the battery powered Sonicare could do as good a job as the rechargeable Sonicare toothbrushes that I have owned since the product was introduced years ago.  Not only does the toothbrush clean my teeth as efficiently as the more expensive rechargeable models, it is great for taking on long trips.  I have not had a cavity in 15+ years - something I attribute to my Sonicare toothbrush.
