Porkie, you really need to get one, I know you love technology stuff as much as I do, and that tent is a perfect example of cool technology in action.
Even if you sleep in the halfords one which is bigger, you HAVE to buy the millets one just to put it up and see how cool it is

And its only 40 quid, thats not even half a bottle of champers!
The downside I found to it was though that if you wear it with the backstraps then due to its large round flat packaging, if you are bald and ugly, you end up looking like a teenage mutant ninja turtle
