i bought the long barrel does cool down the vapor no spitting either .... it leaks all the time it gets hott after 3 drags and two drops only last 3 drags i cleaned it alot to try and fix it .... it made it worse i think i messed mine up alittle .... it still works and to me an i06 hits way harder than it i soaked the i06 in vodka for a day works like brand new
