Review on Enhance Your Network Connection With Dingsun RJ45 Coupler - Compatible With Cat5, Cat5E, Cat6, And Cat7 Ethernet Cables (Black 10 Pcs) by Chris Durandis

Installed Funlux 8 camera sPOE system. Needed to extended 6 sPOE cables to reach the NVR box. All couplers worked great. I also used all 12 of the RJ45 module plugs that came with the couplers. After crimping each plug to Cat5e cables, the plug attached to the Dinger couplers without any issues. I'm wondering if reviewers who said the RJ45 module plugs didn't fit into the coupler realize you must crimp the plugs to an ethernet cable first before inserting it into the coupler. I will definitely purchase again if I need more RJ45 couplers.
