Review on Enhance Your Aquarium with the Yosoo DIY CO2 System Kit Pro for Planted Tanks – Includes Tube, Valve, Gauge, and Bottle D201 by Yolanda Williams

So the first of these items purchased lasted about 1 month. I was very disappointed that it only lasted 1 month. Gaskets are good for lids. However, the valves fall off. The pressure control valves worked for several weeks. After 2 weeks I could no longer close the valves and it kept flowing. I wanted to return it but the shipping was a joke and not worth my money. The instructions warn against overtightening, which I paid attention to. I bought a second set to make sure it wasn't just defective. The second does the same. Doesn't turn off completely after a few weeks of use. But I like the meter.
