GloBrush from Arm & Hammer SpinBrush to review. This toothbrush is perfect for tweens. It lights up and when it changes colors then it is time to switch sides in the mouth. Then once it shuts off, then your kids have brushed their teeth for the 2 minute brushing time! So with this awesome brush, we as parents can at least feel better when it comes to our childrens oral hygiene knowing that they have the best tools to brush their teeth with. The GloBrush comes in three great colors that your kids are sure to love!
