Bin of Bio - CO2 switched to this system. In the Bio CO2 bottle held 30 days as in the description given. Also clogged after 3-4 days of pinball and had to be cleaned, which is not the case here. I also think that with this set the night off and the check valve is. The price was lower than other "brand suppliers". However, I have now found now complete sets which part of components (pressure reducer, solenoid valve) are used in industry and are a little cheaper. Get me soon the joint purchase of returnable bottles and buy CO2 in future in returnable bottles. These can be rented and partially paid for filling very little.
