Review on 🚿 Highly Efficient Brass Ceramic Stem Disc Cartridge Faucet Valve Replacement for Bathroom Kitchen Tap - 1/2" Quarter Turn (1 Pair Hot & Cold) by Walt Smirnoff

When shipped, the cold water cartridge (blue) is disassembled in a sealed bag and the white plastic part is missing. There should be three pieces of white plastic, not two. See photos. without it, the cold water cartridge is useless. This is the second order, everything was exactly the same the first time. A disassembled cold water cartridge in a sealed bag, missing the same white part. The packages were NOT torn in transit so nothing would fall out. The cartridge must be fully assembled, as must the hot water cartridge (red). I think the manufacturer should quickly check their inventory of these parts for quality before shipping another one.
