Review on Keg Cap Accessory Kit For Craft Beer Growler - Maintains Freshness Of Carbonated Drinks, By DrinkTanks by Dennis Long

I love the growler but the c02 only gets me about a cup of beer. I've burnt through 3 c02 tanks just to serve three 16 oz of beer. I feel like this isn't really designed to pour out of the nozzle but simply to keep beer fresh longer. Basically, it doesn't work. I feel like the pressure release valve should hold more pressure for a pour or they should simply design the cap to pour while tipping sideways and the c02 is simply to keep beer fresh. Maybe I'm missing something. If I am, I would like to know what I'm missing. I feel like this is impractical, a gimmick thus far.
