Review on 🔌 VANDESAIL RJ45 Coupler 20Pack - CAT 6 Ethernet Extender Female to Female Keystone Jack Coupler by Kurt Manning

Works well. I had no problems with it clicking or being too brittle. However, I've cut my fingers multiple times trying to move them from one location in my patch tray and to another location. The plastic corners are pretty sharp. This isn't a problem once they're installed and left alone, but if you decide to move them, be careful.
