My Oral B toothbrush came with a little digital clock that sticks on the bathroom mirror, when you start the toothbrush it switches to a timer that counts up, with a little quadrant indicator that changes every 30 seconds. It also apparently grades how well I clean my teeth, but that appears to be based purely on 1 star per 30 seconds, up to 5 stars. |
