Hate to piss on your fire dude (but I'm bustin' for a slash) - but these things - they are no good. Firstly they foamalise the beer to give a 1:9 beer to head ratio; secondly, it's the same as having an extra fridge in your house (we have one back in The Reich (a Becks machine) and the leccy shot through the roof); thirdly, for the same price you could buy a really trippy bottle of absinthe and get properly cunted.
