OBESTBurst Starter Battling Tops B-180 Spinning Tops Set with B-184 Custom Launcher LR Left Right Spin Toys for Kids Children

I don't really understand these toys but my son is very happy with this and assures me it is a good one. Apparently has good attack and stamina (if that means anything to you). Seems pretty solid and well made compared with some of the ones I bought off a well known auction website. Just be careful of fingers and toes as it contains hard metal and does spin very fast (all these ones do). Good value - you get one gyro and one pull string type launcher.
