I'm from Washington so the need for a vaporizer pen is serious. Portable hookahs helped me out in a way that I'll never forget. I bought the kind pen V2 and the chamber was a bit small for dry herbs. I emailed them and they offered to exchange the used kit and allowed me to upgrade to the Truva which produced true vapor. You gotta see this vape, it is amazing! This was awesome because at the end of the day I got a vaporizer just like PAX but with a bigger chamber for half the price of PAX. Thanks to portable hookahs I've been traveling around vaping on the low :)
