My friend suggested me the Spicestyle sonic toothbrush that she bought for her son, so I purchased two toothbrushes. Each of my daughters, who are both under the age of 10 years like the toothbrush as it had made brushing easier and fun. The brush design is clean and simple. There is just one button to turn it on and off, waterproof and made with special anti-bacterial bristles. At this cost, is it best toothbrush.
