Here's the mfgr' page:
Product Catalog - Model MBD5L - 5L Mini Beer Keg
They have a very detailed PDF showing parts, assembly, etc etc etc.
I have a kegerator already, so it's not much good to me -- but I will admit, the first time I saw these in stores, I was DROOLING. It just would've required me switching from 5g Cornies over to the mini kegs, and I wasn't really planning on going that way. (I like 'em, they're just not for me.)
