Greetings dear !your post is very interesting . This is the first time I have heard about this toothbrush and after reading it I am very impressed and I mean this product is specially for people like me . When I wake up early in the morning, I feel sluggish and do not feel like doing any work. If I can found this mechanic toothbrush that do all the work by itself, it's a blessing for me. 😂✌🏼
