Completely unreliable
These solenoids are completely unreliable. I have 3 CO2 generator bottles and I've had to replace 4 (and counting) solenoids in less than three months. After a few weeks the switch fails, resulting in steady CO2 flow overnight. I wish there was an alternative for the system I am using - I guess I'll just have to slow the CO2 flow and have it go constantly. The solenoids are a waste of money - buy a CO2 system that uses a more reliable alternative.
