Review title is Not sure I should have changed.... [SEP] At the suggestion of my periodontist, I purchased this Oral B Vitality Precision and am having a difficult time rating it.  Yes, I think it does the job.  When the brush vibrates at the two minute mark, I am able to keep brushing because it does not stop until I turn it off.  The problem with me is that I have been using the Oral B Cross Action battery operated brush for years and in comparing this new brush to the battery operated, I believe the battery operated Cross Action brush did a better job. My mouth felt cleaner after using the battery operated brush.  Perhaps if I buy the Cross action brush heads for the Vitality Precision, I will be more positive. Since the periodontist told me I was doing a great job brushing (with my Oral B battery operated), perhaps I was too fast to even consider a different toothbrush.
