Manual transmission VS electric transmission! ! Come and post a couple! ! If you love him, let him take good care of his teeth and have a good appetite! Amway's negative ion toothbrush claims to be a toothbrush that does not use toothpaste! ! But I'm still used to using toothpaste, dry brushing feels weird and a little stupid, hahaha! When brushing my teeth, touch the metal sheet with water, it will release a tiny electric current to generate negative ions, and I feel a subtle metallic smell every time I brush my teeth. Press the button to check the remaining power~ (the light is on to indicate that there is power) and it can change the brush head, although it seems that Yami does not sell it, but it is cheap enough! !

手动挡VS电动挡！！来晒一对喇！！爱ta就要让ta好好保护牙齿，牙好胃口才好嘛！安利这款负离子牙刷，号称不要用牙膏的牙刷！！不过我还是习惯用牙膏，干刷感觉怪怪的有点蠢，哈哈哈！刷牙时用水沾下金属片，会释放微小电流产生负离子，我每次刷就感觉到有股微妙的金属味。按按钮可以检查剩余电量噢～（灯亮表示有电）而且它可以换刷头，虽然好像亚米没卖,可是人家够平价啊！！
