Review on Spintastics Spinabolo Diabolo Blue by David Hayden

I bought two of these diabolos for my son and he says that for some reason he thinks one of the diabolos bearings is broken because it might all still work, but the camp just seemed too slippery judging by the movement of his sticks. I thought this toy would make a great Christmas present but it seems to have some issues. I would not recommend this diabolo for players.
