It does a much hated job in seconds and it does it very well.
No matter how fresh or dry the garlic clove is, it always works.
Keeps your hands clean, no long lasting garlic smell on your fingers.
Using it hardly needs an explanation: Just put a clove in it, roll it gently on a hard surface until you hear a crisp sound and shake the garlic out.
A must have for garlic-lovers.
