[OralB]

Finally found out that the Japanese 35000 is a version 4 board.
Also, to vent a little frustration I've gotta say that for as much postive things that have been said about Origa chip on this board...I got to say that some of their business practices have to be questionable at best since they basically ripped me off.
If you doubt me you can ask for for the details. I'd take care and weight the other options before ordering from them.
