This is an amazing toothbrush. It has many new features. It connects with your smartphone to give you better cleaning results because it has Position Detection so you don't louse a spot. It has good battery live. It has a case so you can carry it to your holidays. You can change the color of your toothbrush from your smart phone. The toothbrush is easy use so I am recommending it to my friends and family so can experience the best cleaning ever.
