sonic??
i agree with the above reviewer. if you want a sonic technology you are better off getting $100 SONIC toothbrush. i have used couple of oral b toothbrushes. that include the double spinning one and cross action, the problem i always had was the battery they would not last long. now i don't seem to have problem with this one because i just brush and it goes right back to my charger.<br /><br />i have been using oral b vitality for a month and i have to say i am pretty happy with the result. i brush around 3-4 mins and it feels clean and i could tell the difference b/w the ordinary toothbrushes and the alkaline battery powered onces. even though it will obviously not give you the same sonic technology for $20, i think for me it is worth to spend couple of extra dollars and get better cleaning than ordinary toothbrushes.
