The G5 by YoYoFactory is the fifth yo-yo in the "Project Red Alert" series. It was the first modern H-shaped metal yo-yo in history to be produced and sold. With its unusual shape and free spinning hubstacks, this delivers an all around new yo-yo experience. The H shape allows the weight to be distributed mostly in the rims for easier maneuverability, also making the yo-yo longer spinning and more comfortable to hold. The hubstacks are used to manipulate the plane/axis of the yo-yo for Matador-style tricks, and could even allow the user to ripcord it into a spin, instead of throwing it down.
