Review on 🚿 Brass Handheld Shower Shut Off Valve with Shower Flow Control - Suyar Water Volume Adjust Device, Water Pressure Regulator, and Shower Flow Restrictor in Brushed Nickel by Shalom Germann

Advantages: Solid brass construction, easy installation, high quality internal ceramic flow control. Disadvantages: The highest stage (ie fully open) results in a slight reduction in flow compared to before the valve was installed. (This isn't a problem for me, but be aware of that in advance.) The slider has very angular edges. (They won't intersect, but it would be better if the edges were "softer".),
