Review on 💪 High-Quality Grohe Ceramic Cartridges: Optimal Performance and Durability by Montrell Copeland

I do not believe that this is a genuine Grohe product. It fits and works well, but when installing, be careful not to mix up the order of parts such as the rubber washer and dual ceramic valves. To avoid this there is a plastic cover on the bottom, when the cover is removed everything falls out. Therefore, the entire fitting must be removed by turning it upside down and installed after removing the plastic cap, otherwise it will not work properly.
