no but ive just bought a primo mix after a lot of research into the primo, the wtp and the shadow rant v2. i just saw your other thread about this and dont try taking it apart if you dont need to. if it breaks then fair enough take it apart, but the sound isnt worth the risk of putting it back together wrong because you dont know what youre doing. (im not trying to makeit sound like i think ur an idiot here cos i wouldt do it to my hub either). if you really want to take it apart use a guide. there must be one on youtube or google.
i know how to take it apart and put it back together i was just woundering if it was a problem but turns out it is just overloaded with grease so thanks very much for your help mate =)
