POWER BRAINXP

The Yomega Power Braincontains 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 yoyo slows down, the clutch snaps shut causing the yoyo to return automatically to the players hand. The Yomega Brain is one of the most popular yoyo designs in history and great for beginners.
