The toothbrush has been supplied from one to the other day, 1A. The toothbrush makes a good impression, the brush head is easy to change. The various cleaning stages function properly. For me, the brush is not "strong" enough. I have 15 years of experience with serious and toothbrushes. Aldi, OralB, Waterpik and now last four years Phillips Sony Care My Sony Care dismantled now in items. Since my teeth are free from tartar and plaque (according dentist), I can not judge the performance of the toothbrush. I give it to my 4 year old grandson on. A very good entry-level model. For the price a good buy.
