When trying to connect this system, entweichte abruptly throughout the gas! Despite sealing ring on the pressure regulator, the valve is closed! The result is a severe icing my hand! Now it comes only once to the hospital because I do not know how much gas I inhaled and how bad is the icing! Something really can not be. These are guaranteed to no incorrect operation!
The product is immediately Dennerle with medical opinion. Now we'll see how it goes. I will report here!
