There are at this "premium model" no real added value. Apart from the Oral-B Vitality, toothbrushes all have the same frequency oscillating movements per minute and the brush heads as an active element are the same anyway. The SmartGuide is the beginning still fun flipbook. The different brushing modes are meaningless - they extend more time to get a good, plaque-free cleaning results. I myself can not do it to get a good result in the recommended two or three minutes brushing time. The annoying interruptions of the device (in for me at short intervals) are not suppressible and disturbing. The Pressure sensor is not carried out consistently. That is the only toothbrush makes a slightly different sound while brushing and on the SmartGuide illuminates a red LED on. For users who really pressing too hard while brushing that's no incentive to change the cleaning habit. It would be better, the oscillation would stop immediately in this case, and so long to prevent damage to teeth and gums.
The metal application on the body like and easy to clean. The remaining surface is rubberized for a non-slip grip, shows after one year usage but lasting impressions of nails and discoloration.
Basically electric toothbrushes are a great thing, whether with "sound-art" or oscillating brush head. If already Oral-B, then also offers a simple model, such as the Professional Care 500, the absolutely same functionality.
