Out of about 6 people who I have asked this question all say it is really good, 5-10 solid turns and feels sturdy and solid...which is good, but I would still like to know more.
At least it seems they used a different supplier for crown/tube on this, the V5 crown/tube was crap, another issue that was never fixed over 3 years they have been out. Sorry about your V5, only option is to go gen crown/tube, it was bound to happen eventually with these.
