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.
