By the way, how do you open spintastic tops for maintence, like cleaning the bearing? On a side note, my blizzard seems to have a crack running all the way from the tip up to the rubber ring. I have not dropped it at all on any hard surfaces or bumped anything with it, and im pretty sure it came right out of the package like that. The crack seems to be inside the plastic, because I can't feel any ridge on the outside. The plastic wont budge, so its not like it penetrated the entire wall of the top, and it doesn't seem to effect performance at all. It spins very long and has a good balance. I was just wondering if maybe the top could have cracked while it was being made? I'm not sure how they are made, but perhaps during the molding process?
