OK got the replacement and the Aerotank fits perfectly!
So a new problem......
the minus button has gone 'sticky' and doesn't click like the plus side! Is this a problem and should I send back again? Or will this be ok? The button still works just doesn't click and feels kind of stuck!
Not having much joy with the Vamo's am I wondering whether I should have gone with something else?!
i have a v5 and batter it every day some tanks push down the center pin just flick it up when it happens or like i have fit an air flow connector it solves the problem and saves ant 510 thread problems and if using pro tanks gives a better draw
