This is a smart juicer where you simply half your citrus fruit and squeeze juice against the cone. It has a juicer head that flips from large to small for lemons and limes. The base container has measurements on the container and an easy grip handle. It is dishwasher safe. Treat yourself to fresh-squeezed grapefruit juice every morning! Juice grapefruits are smaller than regular grapefruits. Ask your produce man.
