mine works fine with the button on top, they had all sorts of colours too. u can find them at canadian tire, and walmart caries them to.. it does like to loosen up though, i just tighten it with the allen key now, again

 

Looks like I might make a trip to Walmart soon.

 

me to, see If I can find something good

 

Just came back from 3 different walmarts and NO LUCK.

 

thats wierd theyhad them here in canada last time when i bought mine. red, blue, chrome, carbon fiber look. maybe they stopped carrying at all the walmarts.. sorry guys
