I just got mine from poslaju, coz I was not at home when it came on Friday.

Anyway, been trying it... I gotta say, it's either I am not doing it right or simply dumb or it's damage during postage, I just can't maintain the ball to keep rolling. As soon as I spin it with the starter string, and face it down and move my wrist, it dies off like in matter of seconds. And it keep having the knocking sound.

I will try more after work

dude man.. finally know how to use it haha I am a slow learner, now I can even do the stringless flick I have been rolling it for almost an hour, the entire right arm seems to be numb haha real fun indeed.
