It works great. I brought it to a family reunion with two 3-gallon kegs and we just kept draining & repacking it with ice each day. I bought a 2nd paintball bottle just in case I had any CO2 issues, which came in handy as my IPA had not finished carbonating by the time I started serving and I nearly drained my first tank (I also think I have a small leak somewhere, but not sure where).
