this review title is: i am happy and the content is: i am giving this a 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 star job and it has already after months improved my gumssomeone 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 years old at the least maybe and i was on my second handle they could be different now all in all i would recommend this highly hope it lives as long as the sonicare brushes lived.there are other information for this review, one is this reviewer did not purchase it and the other is 14 people think this review is helpful.
