Review on PERA 43178-145684 Ball Lock MFL Disconnect Set with Swivel Nuts (2) 5/16 Gas, 1/4 Liquid Barbed - Pack of 2 by Molly Kaye

I've been using (and abusing) them for 3 months now. They have been connected about 50 times (beer side) and more than 100 times (gas side). Ever since I started kegging and swapping the beer keg back and forth between different kegs and swapping the gas line between my drinking keg and the forced carbonation of a freshly poured beer. Soon I will add two more taps and gas lines. But these two ball locks held my abyss well at the same time. Best of all, despite my inexperience with the gear, there are no gas leaks, which I at least partially influence the quality of these ball locks.
