Very disappointing...I want my money back...
I've used the dual head Oral-B Vitality toothbrush and was very happy with it because the bristles actually move and your mouth feels extra clean. THIS "Sonic" toothbrush is a sham!  The bristle don't move!! The entire toothbrush merely vibrates which is probably what causes the 20,000 "movements" per minute.  Very very disappointed...don't waste your money on this, I recommend the Oral-B Vitality Dual Clean Rechargeable Electric Toothbrush instead.
