Definitely the wrong bearing shipped with mine. The Konkave shipped on the yoyo is fine. The other one is not wide enough and the string binds around the axle inside the bearing. Ruined my axle trying to make it work. Somebody should make this right.
As much as these cost, they should ship everyone a new axle and the appropriate bearing.
