They serve their purpose. Getting balance was trying at first. Highly recommend turning the CO2 pressure on your kegs a few days before taking them "on the road" way down so these will be easier to balance.
This item is ok however it was delivered with the dispensing portion loose. Since I am new to brewing I did not know to check this. As a result beer flowed without the ability to stop until I removed hose from keg. After 2 tries I found the loose pieces and tightened, then it worked. Based on packaging I am not sure who is responsible for the quality check.
I have to give this a bit of ding for the use of the lower quality ball lock connector. I was having trouble with flow and foaming, changed the ball lock connctor to one with a metal pin to push in the poppit valve, and my foaming and flow issues went away. Such a simple thing, but the same ball lock connector was used on the jumper assembly. I am paying about $7 locally for a much better ball lock connector, but it is worth it.
I've never had luck with this thing. It doesn't hold the gas pressure well and leaks (squirts) beer. I ended up just using the beer line to hook up another draft faucet assembly in my kegerator. I ended up buying item #KEG902 for a party tap.
I have beer line all over the place since I have my kegerator and lots of parties outside with friends. I like to have plenty of extra of these just in case of a unknown party down the street or replacing some of the lines I currently have in use.
This basic ball lock beer line assembly is all you need to serve up your wonderful brewskies. I bought this for my 2.5 gallon stackable corny and it works flawlessly. The construction and material is high quality. Without doubt there will be good times and you will be not be dissapointed.
