I have been using the sonicare brand of electric toothbrushes for some years and its on the my best purchases. I know they now have some newer models and I would like to buy one of those as they seem slimmer than teh older models.

The one improvement I would like to see (and this may have changed since I last investigated but I dont believe it has changed) is a dual charger as I travel alot internationally and its inconvenient needing two chargers and toothbrushes because one cannot buy the charger seperately.

Aside from that small issue, I love the toothbrush and replacement heads are very easy...
