Duncan Reflux Yo-yo

 The Duncan Reflex yoyo is Duncan's first automatic return yoyo. Auto return means that when you throw the yoyo down and make it sleep, a clutch will kick in and make the yoyo wake back up automatically when the yoyo starts to slow down its spinning.

Yoyo pros don't need auto return yoyos, because they know how to make a yoyo wake up. But for beginners at yoyoing, an auto return yoyo can be useful and can help avoid the frustration of not being able to wake up a sleeping yoyo.
