Wow, I went to the brewpub while visiting Lubbock, TX and they have started serving party pigs for $30. I thought, wow that is pretty good pricing for a case of good beer. I was also thinking how perfect this things are for taking on a trip. If you haven't seen one of these you should check it out. I plan on buying two and rigging them for the little CO2 cartridges instead of the self inflating ones they are sold with, but other than that these are a perfect solution for fridge room and to-go party beer. I would never think about using a Mr. beer or anything like that, but this product is extremely durable and fits inside a cooler with ease. They even have a model that comes with a cooler with the tap hanging out. I see multiple uses for these and just wanted to put the word about it out there, no affiliation with the company but i give them thanks for a great idea. Its a reusable party ball!!!
