Two batterys an atomizer/cart and a cart sounds good to me
The ideal would be ONE Thing to carry about, and built like a brick. Not a thin metal shell....
IT should carry (Ideally) recharge two batteries, and hold a complete E-cig, and be solid enough to withstand a lot of use/abuse.
I feel like my 510 PCC is a tad fragile. I usually carry a E-cig type case instead, and a complete E-cig as well. That way I've got three batteries, and two atomizers. (Which to me, means two flavors since my atomizers seem to be pretty solid so far.)
Trouble is, I still have no where but my pocket to stick my active cig when not in use. I'd like to stick it, fully assembled into my 'one thing.'
If that 'one thing' was a PCC, all the better.
