I am needing to replace my electric toothbrush. I already have the OralB sonic complete seen here. http://oralb.com/uk/products/power/sonic.asp But it has stopped working so I am either looking to get the same again or the triumph model with smart guide. http://oralb.com/uk/products/power/triumph_smartguide.asp Which is better do you think? I quite liked the sonic one but is the old fashioned mechanical triumph better as Oralb have made this their premium model? Cheers.
