Review on Kohler GP800820 Rite-Temp Pressure-Balancing Unit Cartridge, Single, Black - Enhanced for SEO by Gerald Reeves

Item arrived on time and in the original Kohler packaging with all required o-rings and gaskets. Solved my problem with water being totally cold or totally hot, and it was $22 less than buying from a big store. Installation was very easy, using a screwdriver and pliers. Note: This is an exact replacement for part #GP500520 so don't worry if it doesn't look like the old (boxy) part. It still fits perfectly.
