Vaping, Electronic cigarettes

What's the minimum?

Re: bigger chambers I picked up an Aspire Atlantis for £15 from their site. Holds 7ml and lasts me a couple of days whilst out on the bike.

Thanks for the reminders about the new regs coming in, you can't buy 72mg base soon so I've bought enough bottles of it to last me two years

Got 3L of 7.2% in the freezer now, should last me a while...
