Medical Forum / General / Dentistry / August 2007Oral B Vitality brush
http://www.oralb.com/us/products/power/vitality/ we have bought one of these and the charging system eludes me..... I have always understood to charge something mechanical contact ie brass, copper, steel, silver, gold contacts has to be made. With the Vitality, the Brush has a pocket in the base with no visible contacts and it sits on a plastic stork 240VAC supplied with absolutely no metal to metal contact. How does it work............. dj When my dentist reccomended a power tooth brush (this was while I was still harming my teeth with fluoride) I went to look. They were about $100 for the rechargable kind. At one point I noticed one in the grocery store for $10, that used replacable alkaline batteries. I can buy a lot of alkaline AA cells for $90, so I bought it. May be some money saving for you, too. Except that you've already bought it.  SignatureChristopher A. Young You can't shout down a troll.
