&gt; so they can suggest specific brushing plans<p>For me that&#x27;s a hell of a stretch.  Just seems hellishly complex for checking the preferred 2 mins of brushing.  Timer sure, especially for the kids.  But, if people see real benefit...<p>&gt; thermostat that they can regulate during peak use<p>OK, that&#x27;s a benefit that&#x27;s difficult to fault.  Wasn&#x27;t aware of any doing that.
