Review on 🔌 VANDESAIL RJ45 Coupler, Ethernet Cable Extender 5 Pack, Keystone Jack CAT6 Coupler Female to Female (2Pack, CAT 6 Ethernet Coupler Extender) by Kyle Mason

10% of the connectors I received had defects that prevented the cables from securely locking in place. See the attached photo for an example of what to look for. Check every detail before installation. The remaining 18 ports worked flawlessly. I used them in a Monoprice Keystone Jack patch panel.
