good but a word of caution for people with sensitive teeth [SEP] the nice thing about this toothbrush is that it uses the same heads as most of oral bs other toothbrushes this is a basic model which probably cleans just as well as their other models the battery lasted me about a week of twice a day brushing and the battery indicator tells you when you will need to recharge it a few brushing sessions in advance do not ignore it too long because it takes about hours to charge it fully but charging it about an hour should be good enough for one brushing the charger is small and does not take up much room in a drawerthe small head really works well for cleaning the sides of your teeth and between them oral b talks about the cupping action and it really works like the polishing tools most hygienists use it even seemed to dig food particles stuck between my teeth but you will still want to floss where no toothbrush can reach if you have gum issues this may be the ideal toothbrush for youthe dual clean head got my teeth acceptably clean faster but it is noticeably bigger and the precision clean head worked better overall for me it is nice that they included two different brush heads so you can see which you preferunfortunately the slower pulsing action seems to irritate my teeth a week or two after i started using this toothbrush my molars started to ache i ended up returning it and going back to my other oral b whose head looks more like a normal toothbrush which vibrates up down very quickly it does not clean along the gum line quite as well but seems to clean the grinding surfaces of molars slightly betteroral b also sells softer toothbrush heads which people seem to like and may be better for my sensitive teethi added another star for amazons good customer service and considering that most people do not seem to have sensitive teeth in general just about any electric toothbrush will do a much better job cleaning your teeth removing plaque etc etc much better than a manual brush try one if you do not like it a different type may be better for you too
