Review on 🍻 Enhance Your Home Brewing Experience with Joywayus Oxygen Injection System: Oxygenation Kit with Diffusion Stone by Crystal Taylor

No negative ratings yet. It arrived quickly. This is the first one I'm using so I have no comparison. According to the seller it has a 0.5 micron stainless steel stone. The bubbles are pretty good on low but get bigger as I increase the flow. The hose that came with it was better than expected. I think it's silicone. It has no memory like some clear plastic tubes. It took me a minute to realize that the threads on the O2 tank and valve are the reverse of the propane tanks (counterclockwise to tighten the threads). I recommend this product.
