So a bunch of stuff came by priority mail yesterday...
The Smoktech cartomizers (1.5ohm) that came, they seem stiffer than the one I got from my local guy. With the 650 mah battery, it was a good pairing. I enjoyed it. I think filling and vaping a couple of those per day with the 650 and 400 mah batteries is going to be a great small kit, and a lot easier than messing with all the eRoll tanks. I love the idea of wearing the 400 + carto on a lanyard (yeah, I'm a dork).
Would still love a 400 or 450 mah eGo style AUTO battery!
My eRoll will become my "work-only" kit, since I need something very low profile for when I'm on professional photo shoots.
IDK about a 400mAh eGo, but have you looked at one of THESE? 300mAh, Auto
