Received my GS Air-M this afternoon and so far I'm loving this tank. I've not had any leaking or gurgling problems and I have been running it at 14.5w on the Istick. It is a tight fit to fill but I used a dropper and it really wasn't that big of a deal. Loaded up some Crème Brulee from Nicoticket and the flavor taste much better in the GS Air but that stands to reason. I'm probably not the best person for comparisons because I have been using a Protank 2 and this is my first "big girl tank".
Trying to decide what flavor to put in the 2nd one for more testing, but can't stop
vaping this CB!
I will definitely be interested in buying more at a later date and need to find some coils for when this one does give out. Which may be tonight unless I get to bed!
