That was me who bought it... god cuetec just started ignoring me. They sent me a replacement butt and it didn't sort the problem. So I think they just assumed I was taking them for a ride, and now they ignore my contact, and when i ring js-sales they say the person who deals with my problem isn't available.
The threads were the same, they just didnt tap the collar dead centre, so the fit is tight and not flush where the joints contact... also your screwing straight into plastic with any cuetec shaft.
I DON'T RECOMMEND CUETEC AT ALL! I PUT MY FAITH/MONEY IN THEM FOR YEARS AND THIS IS HOW THEY REPAY A VALUABLE CUSTOMER!
