Might as well add my obligatory e-hookah thread remark:
Regular Hookahs already produce vapor, this is just stupid and they should be spending their time increasing the lifespan of their products' parts.
Plus, on the website it says that it's a water-pipe, and from my tests, passing vapor through water greatly reduces your vapor intake because a lot of it cools and returns to liquid form in the water. I mean, they probably have a big enough atomizer and battery to give you a decent hit even with the vapor passing through the water, but you'd still be wasting a lot of e-liquid.
