The result exceeded every expectation we had. The Protostar spins as long or longer than most metal yo-yos, plays as smooth 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 that a few throws with this yo-yo may leave you reconsidering ever buying another metal yo-yo again.
F.A.S.T. stands for Fully Active Starburst Technology®, which is the patented technology that makes the F.A.S.T.® 201 so amazing.
