Query: Dental Delight

I've had Sonicare toothbrushes for over 12 years and swear by them. I definitely like the new narrow slanted shaft of the brush head as it's easier to reach back teeth especially behind the last molar. I do miss the timer (30 second alerts during 2 minute brushing time) which this model does not have. However, it's well worth purchasing at this price!
