The Power Spin by Yomega is a plastic yo-yo first released in the 1990s.
The Power Spin is a plastic transaxle yo-yo with a Modified-style body similar to the expensive Tom Kuhn SB-2, and it places the primary mass towards the rims for faster inertia and increased rim speed. The RB II was based on the Power Spin's design, enhanced with a roller bearing like that of the Raider.
It was also licensed to Bandai and released in the Japanese Hyper Yo-Yo line as the Hyper Impulse.
