Review on 🚿 Zengest G1/2 Shower Head Diverter Valve (20mm Diameter): Ideal for Hand Shower and Fixed Spray Head - Includes Tips for Proper Installation with Sealing Gasket by Charlie Maadhadians

This is for the round version. The Nut version actually looks like it might work. The problem with the round version is that you CANNOT tighten it properly. There are 2 flat surfaces but they really can't be used: 1. They are the same height as the rest of the product, not raised or lowered so you end up slipping on the diverter itself and scratching it. 2. The flat areas are so small that I don't know of any instrument in the world that is so thin that it can cover the entire whistle. Then because you can't tighten it properly, it leaks like a sieve. I tried almost 10 different tools to get the job done (you can see all the damage in the picture, and still used masking tape and/or rags to protect the surface. The materials seemed fine, but what is the difference if you can't maybe the walnut version can actually install but I doubt I'll give these guys another chance.
