Yo-Yo Brain

The Yomega Brain yo-yo contains a centrifugal clutch that opens on the down swing, enabling the yo-yo to “sleep” or spin at the end of the string. When the yo-yo slows down, the clutch snaps shut causing the yo-yo to return automatically to the player’s hand. The Yomega Brain yoyo is one of the most popular yo-yo designs in history and great for beginners.
