Roghly two months ago I purchsed my tooth brush from Costco. I use it to brush my teeth and still use it to brush my teeth. When I use it, it makes a brushing sound and it smells and tastes like tootkpaste, when you touch it, it has brisles and a grip and finally it looks like a pink stick with a grip and brisles. I remember when I took it to UCLA and used it in the dorms. I also took it to my uncle's home during 4th of July.
