I really like that Square Keg holds 1 US gallon. So one can get a double growler of your favorite brew. Or even mix a growler each of two different types.
The pressure system has a gauge plus a valve. So one is able to control the pressure. One also knows when it is time to add more CO2 - carbonate home brew, or recarbonate beer you purchased. The valve means that I usually get two tanks from a 16 gram cartridge.
I use my Square Keg to hold the 1 gallon batches from my Beermkr all-in-one home brewing system. The Square Keg doesn't clog even with an unfiltered beer - the pick-up hose is on the bottom but the hose out is on top.
I also like how the Square Keg nicely nests in the fridge - low and rectangular, not tall and round like other growlers.
The Ultimate Bundle is the best value. (Also Summer Scorcher Bundle) You get both:
* The Standard Tap - traditional lever tap.
* The Party Tap - hose with a picnic tap like one sees on round pressure growlers.
* A neoprene carrying case and extra cartridges.
I went back and ordered a second Ultimate Bundle / Summer Scorcher Bundle because the first one is working so well.
