I was just in Fundy with the girl, and wish I had one of these. First off, I needed to bring a bucket big enough to fit the keg (which I could barely squeeze into my car once it was full of all our other eqipment), and then I bought 4 bags of ice for like 10 bucks ... all it would take is 5 trips of not having to pay for ice and this would be paid for. Thought it was a pretty smart idea, assuming it actually works for up to 24 hours
