Welcome to the AirHeads club.OK, you are all on my 'Thank You' list! I've have had my GS-M now for 4 days and I love it!! Never got into the Nautilus craze 'cause I was happy with my Aspire tanks. Now, between those and the GS-M (which I intend to get a few more of when my vape budget is in better shape - a/c went out and that cost some serious $$) I will be a happy camper. Just two types of tanks, two types of coils----yep, that's a good thing!
