Recently, I ordered the Kanger subox because a few of my friends told me to stop using mech mods to vaporize my eLiquid. I contacted portable hookahs by email and they gave me an entire selection based on my needs. I just received it and now using it throughout the day without punishing my lungs with the hot vapor mech mods produce. I can't believe how much time the rep invested into making sure I was happy with my order. Thanks to this company!
