did you get some defective cartos ?
well Yes and No
they're the wrong size connector threads in boxes marked 510, yet on 510 PVs, the threads wont even grab.
The cartos may be alright- just makes me laugh....as this is a first.
btw, I did write the vendor....they didnt have the courtesy to reply.
I know its not that big a loss at a couple of bucks per carto but
I would like them to know- so they can alert SMOK to the issue.
