Folks I would like to think that my breath smells great and of course I do. I was introduced to the world of powered toothbrushes from my wife. Hey I was comfortable with my traditional toothbrush. But along come my with with this battery op thing, so I gave it a try. You know the saying that it takes 21 consecutive days to form a habit whether it be good or bad. So formed this habit of battery op toothbrushes. I loved that thing, but I kept having to buy batteries all the time. I hated to use it when it just bearly hummed along. So I was in the toothpaste section of WalMart and I noticed this Oral B thing, thinking that it was overpriced I ignored it. About a month later and maybe $6 worth of replacement AA batteries. I thought about that Oral B gadget again. So I purchased 2 of them for myself and my wife. We love them. After cleaning with it your mouth is refreshed and renewed. Don't worry you won't get shocked. There are no metal contacts on the base of the brush. It can also last 2 weeks without a charge so you can take it on vacation without the charger base. I brush about 2 minutes with it. It actually gives my gums a nice message.
