Review on 🔌 2-Pack Ethernet Couplers, RJ45 to RJ45 Inline Adapter LAN Female to Female Connector – Compatible with Cat8/Cat7/Cat6/Cat5e/Cat5 Ethernet –Ideal for Router, Switch, TV, PC – White by Doug Hook

I have several styles of these adapters. They appear to be very well built. Have used one before and had no problems. I bought 5 packs but want to buy 10 packs. I've bought inexpensive (cheap) plastic disposable feedthrough wires from China a while ago and none of them have worked. So take such reliable ones. They are also white and easily writable for identification.
