I ordered myself the Hotbox a few months back online while working long distance (still am, abstained from smoking for 4 months now, got another 2 months to go :P)...
However, I had the opportunity to fly back home for a week off a few weeks ago and I came home, got the Hotbox out, and sadly found out its the US plug :( - The design itself looks very neat.
Luckily I wasn't planning on toking up :)
So yeah, for those people out of the Unites States, I'd be cautious of this, just a heads up.
