It's okay.
You only need to use 1/4 of each tab at most. I gave my daughter a whole tab and within seconds she looked like a zombie with goo dripping from her mouth. We had a good laugh over it. The product did work and I was able to show both of my kids why I am always nagging them about proper brushing. I'm giving it three stars because the product arrived without a box and no instructions.
