Nice timer-tooth brush but not for serious coffee drinker
I liked the timer in the tooth brush that buzzes every 30 seconds so you spend the time on all four quadrants (top/bottom/inside/outside). The whitener didn't lighten the yellow of my teeth from years of coffee drinking, in the first month of use. I am guessing I would have to give up my two cups a day habit for the whitener to be effective.
