What you're talking about is really common when folks first start vaping, but the inevitably short life span of those little 180mAH batteries soon gets on folks nerves, and then before you know it you'll be happy to walk around with any e-cig in public... ultimately, it's about keeping off the dreaded fags, and what other people think is of no real use or interest...
I was out and about in Wetherby (Yorkshire) on Saturday, with Provari in hand, with ext cap & Smok DCT Tank on top - a big combination, lol, but sod it...!!! It's not about what other folks think, it's about having the freedom to do what makes you happy and keeps you off those dreaded stinkies...
