Review on OneBom Stainless Fittings Disconnect Homebrew by Sarah Cox

Reading the reviews I ask myself "Am I missing something?" as I have tons of questions: 1. I bought a pair with spikes - one came with a deformed gasket when screwing the coupling to the head.2. Then I ordered 4 pairs with removable spikes: 2.1. Two of them leak gas at the MFL connector - they cannot be tightened with air. 2.2. Two beer leaks somewhere on the MFL port or between the top and bottom. 2.3. One has trouble with the 1/4" MFL screw on the spikes - it doesn't take bits (can't screw anything)! 2.4. After cleaning they are very difficult to turn - the inner seal creates friction which stops this two halves from fully screwing in. 2.5. Non-standard internal gaskets are used - I've tried tubular ones (these come with flat ones) but they don't fit. Fasteners, gaskets swapped, Teflon wrapped. Dear Law, I Me tried so many things i lost two 5lb CO2 tanks because of it they are surprisingly flat seem strong and durable but i cant get them to work everyone has different problems no troubleshooting instructions no instructions , no link to spare parts I think for 120€ I should get something for them although they are a good weight.
