Just to say whilst the majority of this product is good the tank unscrew procedure sucks royally. Unless you have a pair of pliers it's virtually impossible to undo the tank for a refill.
Luckily I own a Leatherman but anyone who finds themselves having to re-fill this vape without any such tool is screwed. I understand the need to ensure a good fit without risk of leaks but this renders the Mini Nautilus useless to alot of people.
I have been using mine for many months now and whilst it functions in all other aspects it's still a b$rtard to re-fill. As such I have come across a number of potentially interested customers only to be dissuaded by the incredibly poor re-fill design.
I fully expect a poor response from the Aspire team in reply to this criticism and non-ownership of the problem as I've read in previous messages on this board. Suprise me Aspire team, I dare you?
