The YoyoFactory 888x is a very ballenced, well spinning yoyo. It is small, not too small but not too big. just perfect. for size i would rate it a 8/10. for ballance i would rate it about 9/10. spinning time is pretty long, i have had it scence christmas and i timed it in the middle of march and got like 4:30 or something, 8/10. the only thing i dont like about this yoyo is, it scratches REALLY easy! i got a buch of scuff marks all over it for putting in on my yoyo holder! 4/10 for being scratched easy.
