Auto-return clutch, complimented by starbursts (Clutch can be disabled via switch)
The Power Brain XP by Yomega is an auto-return yo-yo first released in 2011. It is a variant of the Power Brain featuring Smart Switch technology. It also uses the same type of clutch as the original Power Brain, but now the user has the option of either leaving it enabled or disabled. Disabling the clutch using the switch allows the player to perform more advanced sleeping tricks with the yo-yo. It's having an auto-return and transaxle yo-yo all in one package!
