Hi Kas - do you think it matters that this one is INR (vs. AW's IMR)? Does it matter that this was a flat top and the button top has been added by a 3rd party? Also am wondering if the addition of the button top will still allow it to fit our Provari mods? And why does this vendor (imrbatteries) have a warning not to use w/e-cigarette, vaporizer or similar device? Do you think this is just to protect them from possible liability? (it's a scary warning and other websites do the same - 18650batterystore.com)
