hi everybody I just pick up the istick pico at the local vape shop and out of the three kits I've got the others being the kangertech topbox mini and the dripbox I must say the pico is my favorite by far the only thing I can think of that isn't superior to the others is tank capacity but that aside it is a awesome mod and tank combo and to me a really great vape. but I do have questions and invite and appreciate all answers. is the firmware upgrade available yet? and if not does anyone know when it will be? thanks for reading and for the help
