Review title is I'm Happy [SEP] I'm giving this a 4 only because you will still need to floss if you want to really take care of your teeth.  As far as brushing goes, it does a 5-star job and it has already (after 2 months) improved my gums.<br /><br />Someone said it felt too unsubstantial after having had a Sonicare.  I, for one, am happy to have a lighter toothbrush do a better job than the heavy one (I admit, I had a really OLD Sonicare--the charger must have been over 10 years old at the least, maybe 15, and I was on my second handle--they could be different now).<br /><br />All in all, I'd recommend this highly.  Hope it lives as long as the Sonicare brushes lived.
