Yo-yos That Return on Their Own

Which yo-yos return to the hand by themselves or catch back on the string?

Duncan Reflex Auto Return Yo-Yo: It returns without the player tugging the string. A clutch engages around the axle as the yo-yo loses spin. No other checked fact states that a product returns on its own or catches back on the string. For the Duncan Butterfly String Yo-Yo, the checked fact is: It has a fixed axle and plastic body.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from. A dash means no checked fact fills that cell. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
