I can allow myself after the short test period, no opinion on the effectiveness, durability, etc. these toothbrush. But the fact is that thanks to their daily tooth brushing drama finally over. Our son loves his toothbrush and can be wonderfully clean your teeth with it. The brush is comfortable to hold and the head is already small and soft, perfect for a child's mouth. The design is a matter of taste, Cars halt. My case rather not, our son found it super. And that's the main thing.
