I have no clue who made it I've been using it for a few years and my keezer dies on me so im buying a sanyo mini fridge because it takes up less space so I wont be needing the keg anymore since I will have no room for it.
It works great I even have extra dip tubes and popet valves for it.
If your doing 10 gallon batches and have a keezer this thing is the cats ass. You can also use it for a fermenter by putting a relief valve and pressuer gauge on the gas in carb your own beer for free.
If I do not sell it thats something that I will mostlikely do.
