The installation was easy and only took a few minutes. Don't over tighten, or you won't be able to rotate the valve. I haven't tested the valve to see how air tight a seal is formed, but based on the snug installation, I expect it to work well. It meets my expectations.
Pros: Snug installation, seems to create a tight seal
Cons: None
