This Review Title is Great for preteen kid.  And simple and the content is: Getting my kid to brush his teeth for 2 minutes (with integrity) was a regular battle.  But with this, even if he spends 1.5 minutes, it is equivalent to 5 minutes of hand brushing.  We are both very happy.  :-).There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
