The grip is very comfortable: a silky plastic, a rather thin brush for an electric toothbrush, a comfortable shape. Many possibilities: Cleaning, polishing, whitening ... When I have the time and inclination I pass from one to the other. Charging takes a good week, and there is a yellow LED that indicates when should reload with at least 2 brushings in advance (I did not try to exceed this time). This works well since I do not charge the brush beside the sink but in the kitchen, and I can do charge with night electricity. Very expensive but with the discount promised by Philips (I expect yet) the price falls below 100.
