i heard that there is xcon problems anyone here want to explain
They were more prone to cracking, so they made an upgraded version of the X-Con called the X-Convict.
where
its on this site
where and, where on the yoyo
what does that do good it’s just a product, not an answer
DarthVaughn told you it was on this site, you asked where it was and you also asked where are the cracks on the X-Con, so I answered to your first question and told you were the X-ConVict was. I don’t know where the X-Con cracks because I’ve never seen one before. Simple. 
I can say if you find an X-Con without cracks then it has never been played.
The X-Convict is a much better yoyo. Basically the same but better plastic.
Also if you know what one looks like then you should know where the cracks are.
They are in the plastic.
nononono, i asked where the cracking was when samad answered, i meant where is the cracking, not where is the page for it
