I've always been an opponent of electric toothbrushes, to my dentist has advised a sonic toothbrush due to gum problems. I opted for the Pulsonic Slim, because it is so small and handy as a normal toothbrush. It is the quiet and the teeth feel an incredibly clean. A huge difference to a normal toothbrush. The Slim is very quiet. Let's see how long the toothbrush runs correctly. So on the first impression I must say that I would buy it again.
