I've been smoke free and vaping for 6 months now. I started with V2 cigalikes and moved to V4L Zeus batteries. The last 2 months I've been using the 20w iSitck and nautilus Minis. So yesterday my 50w iStick came in the mail and I'm waiting for the Kanger Subtank Mini to get back in stock to order that. At this point I feel I should be good for a while. I just feel like in 6 months time I've upgraded a lot and and hope I can stay with this setup without the need to feel like I need to upgrade again.
