The product squeezes out toothpaste through a vacuum pump. Therefore, when installing the toothpaste, make sure that the toothpaste is installed in place, without gaps, and no air can enter. When you use it for the first time, you need to manually squeeze out the air in the toothpaste to fill the cavity.
Every product is unique, just like you. If you're looking for a product that fits the mold of your life, the Automatic Toothpaste Dispenser is for you.
