I just got my Hspin Cut late at night and after a while decided to do a couple of offstring throws with it (over carpet)(and yes i know a dumb idea). then the next morning i took it to work and had forgotten that i didnt put the string back on the bearing. So i threw it down as hard as i could not thinking and there it goes a 1000 MPH on the cement! it came apart and i almost lost my bearing too. i was nearly brought to tears in front of a couple of co-workers!!
