i own this toothbrush and i must say this product is great. i have seen a huge diffrence in my coloring of teeth and my healthiness of gums after using this product for a few weeks. i think this toothbrush is what every family needs. it has a whitener a self cleaning sanitizer and has massager for gums. its an all in one product that cleans every part of your mouth. this is the best purchase i have made when i bought this.
