If you have a bit of Problemzähnchen how my kids (even without clasp) to get to the big or the kids do not really essays on, a little later standing incisors ran. These essays works here the reach of the individual teeth better by far. Even 'schallt` the brush much stronger through the spaces between the teeth, do you mean that there is more steam behind it (because the bristles are a little shorter maybe). I'll buy us no other more, that is for me, my wife and. My two Stöpske with 9 u. 10 years. All are very enthusiastic, because we have already tested the great, and the kids essays. Also see my other reviews. Why can not life always be so easy ... If you like this review, but just click on "Yes" or if they still want to know something about it, write me a call. Hope I could help, and now a lot of fun even when browsing, buy, or pondering what they just make up ;-)
