This product works just as promised! Just make sure if your new to homebrew kegging that you get a Beverage AND a Gas connector because they are not compatible with both connections.
I prefer the flare connectors to the barb connectors. I'm always trading kegs of homebrew with my friends and some have pinlock kegs. These make it easy to switch out the connectors for different kegs in my kegerator.
Definitely recommend this over the barbed one. You can disconnect this from the hose for easier cleaning or to make some strange configurations as those needed with a plate filter.
