Abstract
A trial (test) power toothbrush designed to emulate the performance of a corresponding commercial toothbrush, powered by a non-rechargeable battery. The power to drive the toothbrush is controlled by a control circuit which is responsive to the battery to maintain the drive power at approximately the level of the commercial unit and a short 'trial use' period, i.e. one month/30 days, and then to terminate operation of the power toothbrush. The trial toothbrush may then be readily disposed of by the user, including the battery therein.
