Battery powered Sonicare toothbrush
I bought this item for a trip to Europe, as I didn't want to have to carry my charger.  More important than the weight of the charger was my concern about the availability of converters or proper voltage plug-ins to recharge my regular Sonicare, as I was traveling with 2 other people, and we all had cell phone and digital camera batteries to recharge nightly, so I didn't want to take up valuable plugs.  I have used a rechargeable Sonicare toothbrush for years, with great results.  This one works just the same, and the original batteries lasted for the entire 3 weeks (and it's still going).
