The Protostar spins as long or longer than most metal yo-yos, plays as smoothly as most metal yo-yos, and costs less than half of most metal yo-yos. With Yoyofactory's Center Trac bearing as a stock feature, the Protostar is competition ready straight out of the box.
Be warned: A few throws with this yo-yo may leave you reconsidering ever buying another metal yo-yo again!
