The Genertia was Japan Looping Solutions' (aka JPLsolutions) first full metal yo-yo made specifically for looping. Its design uses the same basic structure as their popular plastic Loop Up yo-yo. The Genertia's gap adjustment mechanism is identical to the Loop Up and can be adjusted steplessly. Besides using a titanium axle, it uses replaceable plastic starburst rings for the yo-yo's response—the only yo-yo on the market with such a feature. Uses a size A ball bearing axle. While this model is made for looping, it is also an excellent string trick yo-yo for original play.
